摘要
本文提出了利用高分子聚合物壳聚糖-Zn(Ⅱ)配合物吸附尿素的方法。实验结果表明,最佳吸附条件为:室温下,溶液pH在6～7之间,尿素的起始浓度为2.0mg/ml,反应时间为3.0h,最大吸附量可达83.97mg/g。
A method for urea adsorption by chitosan-Zn(Ⅱ) complex was studied.The optimal conditions were obtained fromexperiments.The adsorption capacity of the complex for urea was 83.97mg/g under room temperatur and pH value between 6～7,while the original concentration of urea was 2.0mg/ml.The adsorption time was 3.0h.
