本文采用再生纤维素作基体,通过丙烯腈的加成反应引入氰乙基,再在羟胺的甲醇溶液中作用,获得一种球状再生纤维素偕胺肟螯合树脂。本文详细讨论对这种树脂制备反应的影响因素以及采用正交试验优选反应条件。通过红外光谱分析等实验对树脂的性能进行研究。实验结果表明:以上制备的树脂对某些金属离子具有选择性吸附。 In this paper, regenerated cellulose was used as matrix to introduce cyanoethyl through the addition reaction of acrylonitrile, and then to act on the hydroxylamine in methanol solution to obtain a spherical regenerated cellulose amidoxime chelate resin. This article discusses in detail the factors that affect the preparation of this resin and optimizes the reaction conditions using orthogonal experiments. Through infrared spectroscopy and other experiments on the performance of the resin. The experimental results show that the above prepared resins have selective adsorption on some metal ions.
