Abstract

Zeolite as well as molecular sieves are a class of aluminosilicate materials, which have found wide use in industries for separation, purification and pollution control. In the new era of nanomaterials in the 21st century, these nanoporous materials have become more widely used in separation, catalysis and environmental management, even in microelectronic and energy storage sectors. The following briefly shows the great potential of natural zeolites for some important environmental applications: CO2 removal from landfill gas and coal seam gas using Pressure Swing Adsorption (PSA) with Clinoptilolites: Natural zeolite is not only a cheaper solution to the economical storage system of methane for NGVs but it also present a safer storage medium as alternative adsorbent such activated carbon is flammable and very costly. There is also an increasing interest in indoor air quality control issues among the building industries and health organizations. It has been demonstrated that clinoptilolite is particularly effective adsorbent for odours and some volatiles in indoor environment. Another area of importantnce of natural zeolites is the solar energy application. Zeolites can adsorb water vapour and create effective cooling with solar heat as the energy to regenerate the zeolite. Systems using zeolites can be designed in such a way that combined cooling and heating can be achieved at about 40-60% efficiency. Adsorption of Nitrogen and Oxygen in zeolites for PSA application Cp zeolite deposit has about 75% of the capacity of a commercial Mordenite zeolite for air separation at 30°C. The dynamics studies showed that Cp zeolite is suitable for N2 and O2 separation due to their large difference in adsorption kinetics.

Abstract

The natural zeolite was treated with alkali (NaOH) solution and heating at 100 oC for 12 and 24 hours. The natural zeolite was collected from Gunungkidul, Jogjakarta, Indonesia. The series of NaOH solutions was 0.5, 1.0, 1.5, 2.5, 3.5 and 4.5 M. The final product of the reaction (precipitate) was designated as ‘activated natural zeolite (ANZ)’. The cation exchange capacity (CEC) of the ANZ increased with increasing NaOH concentration up to 1.5-3.5 M. Treatment with NaOH 3.5 M and 12 hours in period of hydrothermal reaction resulted in a maximum CEC (395.6 cmol.kg-1). The maximum CEC also observed for treatment with NaOH 1,5 M, but consumed a longer time (24 hours). The increase in the CEC of the ANZ about 300 % higher than the original one. The XRD (X-ray Diffraction) peaks of the ANZ appear at 2.7, 3.2, 4.1, 5.1, 7.2 Å, this indicated a new crystalline matters (possibility phillipsite) present. Electron micrograph showed that the ANZ has a large cubic/prismatic structure with a perfect form.

Abstract

Planting media and host crop play an important role in determining inoculum mass production of Mycorrhiza arbuskula (CMA). Planting media used in this research consist of zeolite, sand, and soil and the host crop are S. bicolor, S. splendida, C. javanica, C. pubescens. Host crop S. bicolor could be respectively replaced by S. splendida with zeolite as the best planting media in order to produce mass of CMA. In the other hand, mass production of CMA by the combination of S. splendida and soil as planting media could work well under condition that inoculum added in twofold dosage. Using of P. javanica and C. pubescens with zeolite as a planting media was found as the best combination. And the combination of C. pubescens and soil as a planting media could be used also under condition that inoculum added in twofold dosage.

Abstract

Some natural zeolite types have been exploited for long time to improve the quality of mine waste water. This research was to study the effect of natural zeolite from Lampung (Indonesia) to improve the quality of acid mine drainage from gold-mine in South Sumatra. The size of zeolite is 0,045-0,090 mm and it consist of the clinoptilolite, type. The zeolite column was made from PVC pipe with the length of 20 cm and the diameter of 10,2 cm. The zeolite column was leached in saturated condition during 12 weeks and was divided into four times intake of leached samples. Waste mine water taken from the location of Barisan Tropical Mining (Rawas gold project, Indonesia) on 21 and 23 July 1998. The water samples from pit Berenai contain relatively high iron ( 28 mg/l) and mangan of 9 mg/l, while zinc is less than 2 mg/l. The water generally very acid (pH 2,9) and contained the sulphate until 250 mg/l and the value of salinity of 28 mS/cm. The water sample from sediment pond and mining river generally contained iron, mangan and zinc lower compared to Berenai pit. Leached through zeolite column in the end of experiment contained of iron less than 1 mg/l, while manganese only a little changing. For water sample from Berenai pit, the column of zeolite reduced the sulphate content become 66 mg/l, decreased the salinity to less than 18 mS/cm, and increased the pH to 6,5 or more. The results indicated that natural zeolite from Lampung can be used to improve the quality of acid mine drainage. However, the application of the zeolite for larger scale still need detailed study.

Abstract

Two studies of zeolite application on oil palm seedlings for repair media of planting using a sandy soil type to seedlings media of oil palm have been conducted by The Oil Palm Research Center at experimental garden Aek Pancur, North Sumatra. Research I using Typic Udipsamment soil with 4 dose level of zeolite (0,50,100, and 150 g / polybag). Research II using tin tailings which treated zeolite soil amelioran materials, empty fruit bunch compost, dolomite, and also compared with the top soil is Typic Hapludult. The study I showed that application of zeolite is generally able to increase nutrient content in soil and soil cation exchange capacity inclined growth of better seeds. However, at doses of 150 g/polybag, zeolite application actually lowers the pH and increasing Aldd was followed by poor seedling growth. The study II using tin tailings as planting media, zeolite application has not yielded as good as empty fruit bunch compost applications to support seedling growth and nutrient uptake. Continued research related to determining the appropriate dose, and combination with other soil amelioran materials to increasing effectiveness of zeolite in improving the physical, chemical, and biological soil charachteristic as a medium sand fraction dominated planting of oil palm breeding is still very necessary.

Abstract

Nowadays, Indonesia suffer a serious economic crisis. The situation is mainly caused by national industrial development strategy which is depend on import materials, e.g. in agriculture . In the cases, the national need are depend on import fertilizer, so that makes the national food stock become decreasing. This research is designed to offer another alternative in preparing and producing own fertilizer that we need, to solve the problem. New compotition of Animal manure has been made by addition of natural zeolite to gain a high nitrogen content. Characterisation analysis of materials included chemical composition of natural zeolite and manure fertilizer using AAS and Kyedhal analysis, structure analysis by XRD and SEM and CEC. The result of experiments showed that addition of natural zeolite to excrement (animal waste) increased the content of nitrogen and decreased the content of water in manure fertilizer. Ammonia absorption by natural zeolite with particle size of either –8+14 or 14+20 mesh was almost similar. The nitrogen content of manure fertilizer which mixed with natural zeolite from kedung Banteng , Malang was bigger than that which mixed with natural zeolite from Cikancra, Tasikmalaya. The adsorbtion of water by natural zeolite of both particle sizes was also similar. Manure fertilizer which mixed with natural zeolite from Kedung Banteng was dryer than that which mixed with natural zeolite from Cikancra, Tasikmalaya. The improved animal manure has better properties like a high nitrogen content, dry and not malodorous.

Abstract

The zeolite membrane of MFI could be sinthesized on alpha alumina support having an asymmetric structure and a pore diameter of top layer being about 0.1 μm. In this experiment, the method performed was a hydrothermal process being done at temperature 303 K by using Silica colloidal with the the composition of 30% SiO2, 0.04% Al2O3, 0.4% Na2O and NaOH 4N. The membranes produced were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray diffraction (XRD), Energy Dispersive X-ray Spectrofotometer (EDX) and gas permeation, which use some pure gases such as carbon dioksida, methane, n-butane and ibutane. Based on the SEM observation, the top layer of MFI zeolite membrane produced was about 20 μm. The Analysis and mapping by using EDX showed that the zeolite membane was formed on top and inside of the support. Based on the gas permeation test, the permeance of nitrogen increased while the temperature encreased, and the result showed that the permeance ratio of n-butane/i-butane was about 60. Meanwhile, the selectivity of n-butane/i-butane at 300 K was 62. The simulation test of gas separation was performed by applying the mixture of nbutane and i-butane as a model and the temperature variation of 300 K, 340 K and 380 K. In this case, the Test used a pervaporation methode in which helium as inert gas (i.e. sweep gas) and on line analysis by using gas chromatography. The Flux of gas being through the membrane was measured by flow meter. The Selectivity of the mixture of n-butane and i-butane at temperature 300 K obtained was 62, and its selectivity decreased while the temperature increased.

Abstract

Sweet potatoes are more sensitive to fertilization of Nitrogen (N) and Potassium (K), among other macro nutrient elements. Theoretically, in order to produce one ton of this comodity, at least 3 kg N, 9 kg K, and 2 kg P are needed. But in fact actually, urea as a Nitrogen source that might be added to soil commonly evaporated in other way the KCl as the Potassium fertilizer easily leached down from soil profile and thus the plant productivity much lower. Objectives of this research are to study the influence of zeolites addition to increasement of nutrient absorption in soil by Sweet Potatoes. The research was conducted from February - June 2003 in District of Katibung, Jati Agung, Merbau Mataram, then from March-July 2003 in District of Panjang, and April-August 2003 in District of Waway Karya by using Complete Randomized Block Design with 3 replication. Each plot consists of 7 planting area (sized 35 m2) and planting distance is 100 cm x 25 cm, or plant density 140/plot. Zeolites is applied in application level of 30 % from total weight of fertilizer 350 kg/Ha. Bedeng size measure 30 cm and wide 60 cm. Zeolite used with dose 30 % from or equals to 105 kg zeolites/ Ha, Result of crop yield that showed by tuber weight both the small sized or the large sized tuber are optimalized in treatment C which 105 kg/ha zeolite. It could be explained because addition of zeolites in fertilizer increase the nutrient absorption by the crop planted. In all research locations, treatment C yielded the most beneficiary production of Sweet potatoes. Tuber root weight in Chinesse Fertilizing treatment lower than other fertilizer because the nutrients are much slower released in the soil profile.
