초록

Polysaccharides are very effective adsorbents for heavy metals. In this study, the adsorption characteristics of various polysaccharides for heavy metal adsorption were investigated. Tested polysaccharides were homogeneous polysaccharides such as curdlan, chitin, starch, cellulose, Avicel, and Solka floc and heterogeneous polysaccharides such as zooglan, locust bean gum, ghatti gum, pectin, and xylan. Lead(II) adsoption characteristic on these polysaccharides followed Freundlich isotherm and the isotherm parameters were calculated. For adsorption of lead(ll), Avicel, starch, and zooglan were found to be good adsorbents.
