摘要
对羧甲基壳聚糖与Cu^(2+)的吸附作用进行了研究,探讨了反应时间、离子强度、溶液的pH值、羧甲基取代度、温度等因素对吸附性能的影响。与壳聚糖及水溶性低聚壳聚糖相比,羧甲基壳聚糖对铜离子具有更强的络合能力。
The effects of various factors : reaction time, ionic strength,pH value, substitution degree of carboxymethyl group and temperature on the adsorption behavior of copper ions on carboxymethyl chitosan (CMCS) were investigated. The results showed that carboxymethyl chitosan had higher adsorption capacities than chitosan and water-soluble low-molecular weight chitosan.
