Study of Thiolgroups Functionalized PVAgelatin Microspheres

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 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.
