Abstract. The most effective way to reduce the pollution of heavy metal waste is the adsorption process using an adsorbent. Sugarcane bagasse is one of materials that has high affinity to absorb heavy metals. The adsorption capacity of sugarcane bagasse can be increased by converting it to cellulose xanthate. Cellulose xanthate was made by reacting cellulose from sugarcane bagasse with the amounts of carbon disulfide (CS2). Synthesis of cellulose xanthate consists of three process, there are isolation, alkalization, and xanthation. In this study, xanthation process was done by adding carbon disulfide (CS2) as much as 180% (w/w) of the weight of cellulose used and by varying the xanthation temperature at 35°C, 40°C and 45°C. The degree of substitution (DS), the degree of polymerization (DP) and the metal adsorption capacity of cellulose xanthate for Zn2+ and Pb2+ was determined as quantitative analyze. Morphological characteristics of cellulose xanthate was characterized by SEM and the functional groups contained in the cellulose xanthate was characterized by FTIR. The results showed that cellulose xanthate was synthesized at temperature of 35°C has a highest value of DS, DP, and the adsorption capacity than other two variations of temperature (40°C and 45°C). The value of DS, DP, and the adsorption capacity is 0.389, 299.27, 48.353 mg/g for Zn2+ metal and 51.763 mg/g for the metals Pb2+, respectively.
