摘要

研究了酸式纤维素基磁性聚偕胺肟树脂（ＡＭＡＯ）在循环吸溴过程中吸附容量和还原能力的变化

发现原树脂的吸溴初速和溴的还原率比再生树脂高一倍以上

但第一次和第二次再生树脂的吸附速度和还原效率几乎相同

暗示着树脂吸溴后基本结构已发生了彻底的变化．树脂在循环使用时吸溴容量变化不大而溴的还原量却显著降低

表明ＡＭＡＯ作为吸溴剂有较高的实用价值．

Abstract

The adsorption capacity and the reducing power of acidic cellulose based magnetic polyamidoxime adsorbents(AMAO) for bromine in adsorbing cycles were measured.The initial adsorption velocity of original adsorbent and its reduction proportion of adsorbed bromine were found to be twofold or more than that of the recovered AMAO.However

data obtained from the first reactivating adsorbent are almost the same as the second one.Possibly

the structure of the original adsorbent has changed thoroughly after adsorption. The slight variation of adsorption capacity and the rapid decrease of reduction proportion of bromine in cycling adsorption suggest that AMAO is an adsorbent for bromine uptake with an important practical value.
