中文摘要：
以聚乙烯醇、明胶和环硫氯丙烷为原料制备的一种巯基功能化聚乙烯醇-明胶复合微球吸附剂,具有组成可控、尺寸均匀和微观结构多孔性等特点,在高浓度汞离子环境下对汞离子的吸附率可达93.0%,在微量汞离子环境下对汞离子的吸收率为99.2%,并且多次使用后其损失率低于1.0%,是新一代高性能汞吸附用高分子材料.
英文摘要：
Newly thiol-groups functionalized polyvinyl alcohol-gelatin composite microspheres adsorbers were successfully prepared by using raw materials of polyvinyl alcohol and gelatin,and cross-linking agent of chloromethylthiirane.The resulting microspheres adsorbents exhibit definite component,uniform size,large special area and strong absorption ability for treatment of wastewater containing Hg ion.It is shown that the microspheres adsorbers prepared have maximum 93.0% adsorbing efficiency to high-concentration mercury ions and 99.2% to trace mercury ions,and its membrane breakage factor is below 1.0% after repeated utilization.The thiol-groups functionalized PVA-gelatin microsphere will be a potential mercury absorber materials.
