| Abstract: | 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 ... |
| Keywords: | polyvinyl alcohol gelatin microspheres mercury absorber wastewater treatment |
