摘要/Abstract

摘要： 用聚丙烯酸型高吸水性树脂吸收含氟、碘、钾、锌、锰、钼等离子的电解质溶液,分析所形成水凝胶中离子的吸附量,讨论了吸附机理。研究结果表明,高吸水性树脂具有阳离子交换树脂的性质,对阴离子的吸附能力较弱,对阳离子有较强的吸附能力。其吸附能力因离子的种类和浓度而异。

关键词: 高吸水性树脂, 离子吸附

Abstract: In this paper the ion adsorptive behaviour of the high water absorbent resins is reported and the mechanism of the adsorption is discussed. The resins are similar to cation-exchange polymers. Their cation-adsorption power is stronger and the anion-adsorption power is lower. The adsorptive power of the resins varied with cations and their concentrations.

Key words: High water absorbent resin, Ion adsorption
