印迹交联壳聚糖树脂对尿素的吸附行为研究

Study of Adsorbing Behaviour of Imprinted Croslinked Polymer to Urea

合成了交联壳聚糖-戊二醛树脂分子印迹聚合物,研究了溶液的酸度、铜离子浓度对配合物分子印迹交联壳聚糖树脂吸附尿素的影响,以及树脂的吸附动力学特性。结果显示,在溶液的酸度为7、铜离子含量为0．7 g时,配合物分子印迹交联壳聚糖树脂对尿素具有良好的吸附特性。因此,它作为一种新型尿素吸附剂具有广阔的应用前景。

The imprinted cmslinked polymer resins Chitosan - Glutaraldehyde was synthesized. The effects of the acidity of the solution and the concentrations of the copper ions on the adsorbing of the imprinted cmslinked chitosan resin to urea and the adsorption dynamics of the resin were studied. The results showed that when the acidity of the solution was 7, the copper ion content was 0. 7g, the imprinted croslinked chitosan had good adsorbing to urea. Therefore, it would have broad prospects of application to new adsorbing agent to urea.
