摘要

采用预辐射接枝法，将N−异丙基丙烯酰胺（N-Isopropylacryamide，NIPAAm）接枝于聚丙烯纤维。研究了不同条件下接枝纤维对亚铁离子的吸附和解吸附情况。结果表明，在较低温度（5℃）及pH≈0条件下，接枝纤维对金属离子（Fe,2+,）具有良好的吸附性能；而在较高温度（50℃）下pH≈3时，被吸附的Fe,2+,几乎能被较完全解脱下来。

Abstract

An ion adsorbed fabric of PP−g−NIPAAm was prepared by grafting N-isopropylacryamide (NIPAAm) onto PP (polypropylene) fabric pre-irradiated by ,60,Co γ−rays. The ion adsorbility were studied on the Fe,2+, aqueous solution with different conditions, such as temperature, pH and ion concentration etc. The results indicated that the NIPAAm grafted PP fabric possess the ability of adsorbing the Fe,2+, ions at lower pH (around pH 0) and lower temperature(5℃). The adsorbed Fe,2+, ions were easily desorbed at higher temperature (50℃).
