摘要

探索了一种通过聚丙烯(PP)改性来络合金金属的新途径.首先在PP膜上经紫外光引发实施丙烯酸的接枝聚合反应，得到表面带—COOH基团的改性PP膜；再用负离子开环聚合的方法在改性后的PP膜上接枝尼龙6.上述处理后的膜表面含有大量O、N的功能基团，故可将此膜用于对溶液中金的络合.利用ATR、SEM、XPS等技术对改性及络合进行了表征.实验结果表明，此方法制备的PP膜对金的络合效果明显.

Abstract

A novel approach to chelating aurum (Au) by modified polypropylene (PP) was developed. Photo-induced grafting polymerization of acrylic acid (AA) on PP was carried out first

followed by anionic ring-opening polymerization of caprolactam on the above modified film to introduce PA6 chains onto the PP films.By this method

functional groups containing N and O were introduced on PP films. Because these functional groups and chloroauric acid formed the ion-association complex in acid solution

the prepared PP film was used to chelate Au. The obtained films after each treatment step were characterized with attenuated total reflectance (ATR)IR spectroscopy

scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) techniques.After chelating Au

the concentration of Au in the solution decreased from 1 mg/mL to 2.58 μg/mL. The results showed that the films prepared possessed good effect on chelating Au. This study suggested a new approach of chelating Au by modified PP which may have potential applications in reclaiming noble metals from smelt waste water.
