摘    要:聚丙烯颗粒在水溶液中与丙烯腈和二乙烯基苯反应,得接枝交联产物(Ⅰ)。Ⅰ被氨肟化再经成笼反应.得笼形聚偕氨肟树脂(Ⅱ)。笼内仅吸留易于除去的溶剂丙酮。若Ⅰ成笼后再氨肟化,所得吸收剂(Ⅲ)将吸留大量的羟胺,它缓慢地释放出来,干扰吸收剂对酸、碱离子或分子吸附容量的测定。Ⅱ对一些离子例如Hg2+和MnO4-的吸附能力与Ⅲ不同,被认为是两者的网络结构不同所致。

关 键 词:笼形树脂  聚偕氨肟  功能化  吸附作用  吸留作用

Abstract:Grafted and cross1inked product (Ⅰ) was obtained by the reaction of polypropylene particles with aerylonitrile and divinylbenzene in aqueous solution. Ⅰ was subjected to amidoximation and then cage-formation to give a " cage" polyamidoxime adsorbent (Ⅱ).The solvent acetone is occluded into the cage alone, it can be removed easily. If Ⅰ has been formed in cage -shape and follows by amidoximation, the adsorbent (Ⅲ) obtained would occludes a great quantity of hydroxylamine, it releases gradually and interferes with the determinations of adsorption Capacity for acids, bases, and other ions or molecules. The adsorption abi1itY of Ⅱ for some ions such as mercury (Ⅱ) and permanganate differs from Ⅲowing to the difference in their network strructure.
Keywords:cage adsorbent  polyamidoxime  functionalization  adsorption  occlusion
