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(Fe2+)具有良好的吸附性能;而在较高温度(50℃)下pH≈3时,被吸附的Fe2+几乎能被较完全解脱下来。
An ion adsorbed fabric of PP-g-NIPAAm was prepared by grafting N-isopropylacryamide （NIPAAm） onto PP （polypropylene） fabric pre-irradiated by ^60Co 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 ℃）.
