摘要
本课题从海带中提取多糖类化合物,并与丙烯酸接枝共聚、交联,制得了一系列耐盐性能良好的高吸水树脂,其对0.9%氯化钠水溶液(与体液中含盐浓度相当)吸收倍率在70～120倍,对重蒸馏水的吸收倍率为650～1075倍,本实验反应条件温和,重复性好,海带利用率高达72.5%.
The aim of this paper is to extract polysacharide compounds from kelp,one kind of seaweeds, and utilize them to produce super absorbent resins with good anti-salt characters by copolymer-izing and crosslinking reaction with acrylic acid. The absorption ratio is 70 to 120g/g and 650 to 1075g/g in case of 0. 9%NaCl solution and tri-distied water,respectively. The experimental conditions are not very restricted,and the extraction efficiency from kelp is up to 72. 5%.
