淀粉磷酸酯基高吸水树脂对Cu^(2+)的等温吸附行为研究

High water absorbent resin on the adsorption Behavior of heavy metal ions

含重金属离子废水的处理一直是人们关注的重点和难点.近年来,吸附法是处理重金属废水的一种比较有效的方法。本文以马铃薯淀粉磷酸酯为原料合成高吸水树脂,并且检测了高吸水树脂对Cu2+的静态等温吸附性能。讨论了不同丙烯酸中和度的高吸水树脂产品、Cu2+离子浓度、树脂用量和吸附时间对吸附容量的影响,并由X射线光电子能谱验证了铜离子在树脂上的吸附。

Containing heavy metal ions from wastewater treatment has been the focus of attention and difficulty. In recent years, the assay is a more effective method for treatment of heavy metal wastewater. In this paper,potato starch phosphate for the synthesis of suporabsorbent,and to detect the high absorbent resin for Cu2＋ static adsorption isotherm performance. Different in degree of Cu2＋ ion concentration, the amount of resin and adsorption time on adsorption capacity, verified by X-ray photoelectron spectroscopy, the adsorption of copper ions on the resin.
