摘要
以天然高分子壳聚糖为原料,与聚乙烯醇进行溶液共混,研制壳聚糖与聚乙烯醇共混膜.探讨了共混膜对微量Hg2+,Cr(Ⅵ)的吸附性能.结果表明,共混膜具有韧性、壳聚糖不易流失等特点,并且对离子的去除率较高,提高了其应用价值.
The blend film of chitosan and polyvinyl alcohol has been prepared and the blend film were investigated in relation to its adsorption behavior for low concentration metal ions Hg^2＋,Cr（Ⅵ）.The results indicated that the blend film had good properties,hard to be rein of and high percentage of removing metal ions.
