壳聚糖对镉铅混合离子吸附作用的研究
Adsorption of Mixed Cadmiun and Plumbum Ions by Chitosan
摘要
Abstract
Chitosan was used to investigate the adsorption of Cd2+ and Pb2+ ions in a mixed solution. The effects of pH value, temperature,reaction time, adsorbent dose and initial metal ion concentration on the absorption ability were carried out. The results revealed that the Cd2+ and Pb2+ ions adsorption process were dependent on pH, reaction time, amount of chitosan and initial metal ion concentration, but the effect of temperature is not significant. The dynamic adsorption of Cd2+ and Pb2+ ions in mixed solution by chitosan was according to Lagergren equation adsorption model 2, and thermaldynamic adsorption of Pb2+ ion was corresponding to Langmuir adsorption equation. The adsorption capacity of chitosan to Pb2+ ion was higher than Cd2+ ion in mixed solution.关键词
