    Abstract

    ABSTRACT Eka Rakhmawati, 2007. THE USAGE OF CHITOSAN PRODUCED BY DEACETYLATION OF ACHATINA SHELL CHITIN AS REMAZOL YELLOW DYE ADSORBENT. Thesis. Department of Chemistry. Mathematic and Science Faculty. Sebelas Maret University. Chitosan has been made from achatina shell chitin by deacetylation process. Isolation of chitin from achatina shell was done by deproteination and demineralization The chitosan was studied for its ability in adsorbing Remazol Yellow dye. Characterizations of the chitosan are involving determination of water and mineral content, molecular weight, polymerization degree, and degree of deacetylation which is measured by Infrared spectroscopic method. Remazol Yellow dye adsorption by chitosan was done by variation of pH and contact time in order to determine optimum condition of adsorption. Variation of concentration was done to determine isotherm adsorption type that occurred during the adsorption process. The types of the adsorption isotherm were analyzed by Langmuir and Freundlich isotherm. Adsorption and desorption of Remazol Yellow dye in waste water by the chitosan were measured in the optimum condition. The yield of deacetylation process of achatina shell chitin was chitosan with rendement of 9.59 ± 0.71 %. It was odorless, brownish white powder. The chitosan was characterized with 2.06 ± 0.82 % of water content and 26.11 ± 0.45 % of mineral content. The molecular weight average of chitosan was 2 kilodaltons with degree of polimerisation and degree of deacetylation were 12 and 74.95 % respectively. The optimum condition of Remazol Yellow dye adsorption was pH of 2 and contact time of 24 hours. The dominant adsorption isotherm for Remazol Yellow dye adsorption by chitosan was Langmuir isotherm. The chitosan capacity of adsorption in Remazol Yellow dye waste water was 0.40 mg/g with 23.34 % of average desorption percentage.
