摘要
本文以壳聚糖为原料,交联海藻酸钠,制得壳聚糖复合树脂,研究其对Cu^2+的吸附性能。结果表明,Cu^2+初始浓度为200mg/L,投加量为0.05g,吸附平衡时间为3.0h,pH为5.0,吸附效率可达100.6mg/g。壳聚糖复合树脂可用于水体中Cu^2+的富集和分离。
In this paper,Chitosan as the base material was cross-linked with sodium alginate to prepare chitosan composite resin.The result show that,when Cu^2+initial concentration is 200mg/L,adsorbent dosage is 0.05g,adsorption time is 3.0 h and pH is 5.0,the adsorption efficiency can reach to 100.6mg/g.So the composite resin can be used for adsorption and en?richment of Cu^2+in water.
