Abstract

Chemical and physical characteristic of zeolite are use not only as nutrient absorber to increases fertilizer efficiency, but also as compost mixing for plant growth media or compost humidity regulator. This agriculture advantages specially to increases nitrogen fertilizer efficiency. Many efforts carried out to minimize ammonia lost from nitrogen fertilizer, one of the alternatives is using zeolite through the process of making slow release fertilizer. As a mineral with the high rate of cation exchange capacity, zeolite have the ability to absorb ammonium ion, so it will increases nitrogen fertilizer efficiency by mixing zeolite with fertilizer or spreading zeolite into the fields. Zeolite urea capsules use on paddy plant on several regions on West Java showing production increasing and nitrogen fertilizer efficiency increases. Zeolite use as vegetables plant media showing a quite well result. Furthermore zeolite reduces heavy metal take over from the food chain. With these results zeolite have a big role in increasing agriculture production.

Abstract

Zeolite is a group of hydrated silical alumino mineral from alkaline specially sodium (Na), Potassium (K), Calcium (Ca), and Magnesium (Mg). More then 2000 years since it found the first time by Cronstedt on the year 1756 in Sweden have been found more then 50 type of natural zeolite and 150 type synthetic zeolite. The use of zeolite covers a wide range of field due to its ability as absorber, catalyst and ion exchange. However, the use of natural zeolite have several limitation such as limited source, a very high variation mineral composition, and crystal size, porosity and un uniform pore diameter. On the other hand, synthetic zeolite is created to overcome the difficulty and weaknesses of natural zeolite. Several technological research and development have been carried out to increases the economic value of zeolite by exploitation and modifying zeolite capacity as absorber, catalyst and ion exchanger. Zeolite have been used on agriculture, cosmetics, and other industries.

Abstract

Nitrogen fertilizer is one of the fertilizer type which is required for plant growth. This fertilizer is easily dissolved and the ions are not clay bonded, that it is often washed out by rain, evaporated or changed to other forms which can not be used by plants. In order to increase the efficiency of N-fertilizer, the loss of N must be minimized. In other hand, it is well known that natural zeolites have the capability as adsorbents and cation exchangers, such as for ammonium ion. Investigation has been carried out to analyze the capability of natural zeolite from Cikancra, Tasikmalaya to store ammonium ion from ammonium sulfate fertilizer. This research can be used to predict the quantity of zeolite to be added to the soil if we use ammonium sulfate fertilizer. The natural zeolite applied has been selected of the highest cation exchange capacity (CEC) value zeolite from various particle sizes and activation method. The highest CEC, of 150.92 meq/100g is gained by activation at 105oC of particle size "“20 +48 mesh. The optimum CEC of natural zeolite against ammonium sulfate fertilizer is 146.11 meq/100g in 0.2 N (NH4)2SO4 solution. Therefore, the quantity of ammonium sulfate fertilizer (ZA), which can be stored in 100g zeolite is 19.306 g.

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

Naturally, zeolite is a cation exchanger but this property is also depending on porosity, tetrahedral density and frame density. Cation exchange effectiveness can be changed by structure, Si/Al ratio and effective pore size. Tetrahedral group, T, in zeolite is negative charged and can be substituted isomorphycally by other group like PO2+. The new structure can be functioned as anion or cation exchanger. The exchange capacity of both ions depends on Si/Al/P ratio from the substitution process. The alumina-silicaphosphate (ASP) compound has been made from zeolite from Cikalong, Tasikmalaya, with ammonium dihydrogen phosphate (ADHP) with substitution rate between 30-40%. This product has been tested to Pantura groundwater, in Bekasi and Karawang areas,which have groundwater type of NaCl, CaCl2, MgSO4 and CaCl2/CaSO4. ASP tests on ground water samples show decreasing content of Ca, Mg, Na and K cations in ground water by 32.94%, 3.35%, 2.52% and 23.60% respectively. Sulphate anion also decreases by 15.39% but chloride anion shows no changes. Dig-up well of CaCl2 type also shows a reduction of Ca, Mg, Na and sulphate contents by 46.26%, 18.37%, 16.39% and 10.84%, respectively. Dig-up well of CaSO4 type shows Ca, K and sulphate contents decrease of 89.71%, 33.31% and 5.26%, respectively. CaSO4 dig-up well can be changed to Mg-mix type after processing by ASP compound. Cation exchange capacity of ASP compound to Ca is higher than to K, Mg and Na (Ca>K>Mg>Na). Due to a high cation exchange capacity to K and Mg, ASP compound may be used to reduce the hard water level.

Abstract

Research has been done to evaluate the addition of zeolite to manure fertilizer. This research is aimed to review the advantages and disadvantages of zeolites as manure fertilizer additive. Investigation is carried out by different variables: zeolite particle size, zeolite concentration and curing time. The results show that zeolite particle sizes of "“7 +10 mesh and "“20 +48 mesh did not significantly different. Zeolite "“ compost mixture can dry very fast, just in 2 weeks curing time the residual water content is only 5-6%, while that on the controlled compost (without zeolite) is still 70%. Higher zeolite concentration will speed up the compost drying process. On the other hand, zeolite addition will increase the potassium content by 1.7"“2% but it also increases NH3 volatilization, which will result in a lower N content. Higher zeolite concentration will give lower N content in the composite. It can be concluded that zeolite addition is suggested not applied to the fresh compost but just before the compost will be used in order to increase the nutrition efficiency.
