Abstract

Liquid smoke is a preservative solution that can be used safely. This grade 1 product can be also used as food preservative. The aim of this article is to discuss and examine the previous experiment’s results by literature review. The outcome of this article is expected to be regenerated by other research using the existing variable which is discussed on this article or using new variable. Based on the result. There are some variables that effect the final quality of liquid smoke. Some of them are pyrolisys temperature, pyrolisys time, adsorbant type and activator type. Pyrolisys temperature used was arround 250 °C – 300 °C with resulted pH 1.41 to 2.25. While for pyrolisys temperature was arround 4 – 5 hours with phenol content arround 3.04% to 4.08%. The type of adsorbant used was zeoilte and quartz sand, which the acid total having both increment and decrement phenomenon. Activator type used were salt activator such as NaCl , NaHCO, CaCl2, Na2SO4 and base activator (NaOH) which producing the most percent acid total.

Abstract

The need for paper continues to increase, indicating that there is an alternative wood material that can be used as a base for making pulp. Materials that can be used are dried banana leaves which contain cellulose. The quality of the pulp can be obtained by the characteristics of the pulp produced. This study was conducted to determine the effect of the type of solvents on the pulp quality of banana leaves. The pulp has been made using delignification process with addition of 3% NaOH or 3% Na2CO3 3% and heating up to 120 minutes, at 105 °C. Pulp quality was obtained from the results of pulp analysis, cellulose content, water content, physical appearances and qualitative analysis by FTIR. From the analysis of cellulose content, water content and FTIR instruments, pulp made with 3% NaOH solution are better suited to 3% Na2CO3 where the resulting pulp has a water content of 4.96%, a smooth and fibrous texture, a rich color, and produces a cellulose hydroxyl absorption band that is stronger than the pulp made of 3% Na2CO3. However, the pulp made from 3% NaOH solution has a lower yield (56.5%) and cellulose content (26.07%) than Na2CO3 3%. Dried banana leaves can be used as an alternative in pulp making.

Abstract

This research aims to make the chitosan from the chitin of the Snail shell (Pilla ampulacea) which can be used as a cadmium metal adsorbent (Cd). It is derived from the isolation of the snail shells through 2 phases, which are deproteination to remove protein and demineralization to remove mineral salts. The formed Kitin is transformed into Chitosan by deacetylated using NaOH 60%. Kitin and Chitosan were acquired, identified by FTIR. The results showed that the chitin yield was 26.81% of the shell weight of 400 grams and the rendemen Chitosan was 31.78% of the weight of chitin. The results of the identification indicate the absorption area of chitin and chitosan function groups, similar to the standard chitin and chitosan uptake areas. Metal adsorption Cd uses adsorbent chitosan from the shell snail (pilla ampulacea) Most optimal occurs at a contact time of 15 minutes and on the weight of adsorbent 0.25 grams, the most optimal absorption occurs at a comparison of 1:30 weight chitosan/volume solution Cd.

Abstract

One of the way to recycle heavy metals in the prevention of environmental pollution is by using a solid-liquid extraction method through the impregnation mechanism of chelating agent in the adsorbent to increase its ability to bind heavy metal ions. In this study, the impregnation of fatty hydroxamic acids (FHA) successfully carried out on active natural zeolite (ZAA). This is has been done to increase the maximum adsorption capacity of ZAA towards heavy metals. The purpose of this study was to examine the adsorption ability of FHA impregnated onto ZAA as a chelating agent in copper metal ions by using column chromatography. This column contains FHA, which synthesized from crude rice bran oil and impregnated onto ZAA. There are several parameters were investigated, they are, the effect of FHA concentration, mass of FHA-ZAA resin and pH of the metal ion sample. From this study, the concentration of FHA impregnated on the zeolite surface reached 41.60%. The optimum conditions for Cu(II) adsorption by FHA-ZAA were as follows: mass ratio of FHA-ZAA resin with Cu(II) concentration (g : ppm) was 1:100 and the optimum condition of Cu(II) ion was at pH 5.

Abstract

In this research, the effect of rice husk treatment, i.e. ashing to produce rice husk ash (RHA), working with base (BRH), and working with acid solution (ARH) on the adsorption capability of Pb(II) ions has been investigated. Adsorption was carried out by mixing 5 g of the adsorbent with 50 mL Pb(II) solution 100 ppm for 3 hours. The unadsorbed ions were analyzed by AAS (Atomic Absorption Spectrophotometre). Result showed that RH, RHA, BRH, and ARH adsorbents, adsorbed Pb(II) ions with the amount of 86,5 % ; 96,0 % ; 93,4 % ; and 33,0 % respectively. The highest adsorption of Pb(II) (96,0%) occured for the adsorbent of RHA. In the ashing process, the amount of heat or energy might be released and applyed as fuel in various purposes such as cooking and bricks production. Rice husk has multiple uses, besides being a fuel, it can also be used as an effective adsorbent for Pb(II) ions. The study of Pb(II) adsorption kinetics showed that a contact time of 3 hours was an effective time for rice husk ash to adsorb Pb(II) ions. The adsorption of Pb(II) metal by rice husk ash tends to follow a pseudo 2nd-order reaction kinetics pattern.
