摘要
本文以丙烯酰胺和甲基丙烯酸羟乙酯(HEMA)作为原料,过硫酸钾为引发剂制备聚丙烯酰胺水凝胶,在此基础上加入磷钨酸合成聚丙烯酰胺水凝胶杂化磷钨酸材料。以1-丁基-3-甲基咪唑四氟硼酸盐([Bmim]BF_(4))为萃取剂,聚丙烯酰胺水凝胶杂化磷钨酸为催化剂,双氧水为氧化剂,当n(H_(2)O_(2))∶n(BT)=10∶1时,脱硫率可达到98%。
In this paper,polyacrylamide hydrogel was prepared with acrylamide and hydroxyethyl methacrylate(HEMA)as raw materials and potassium persulfate as initiator.With 1-butyl-3-methylimidazolium tetrafluoroborate([Bmim]BF_(4))as extractant,polyacrylamide hydrogel hybrid phosphotungstic acid as catalyst,hydrogen peroxide as oxidant,when n(H_(2)O_(2))∶n(BT)=10∶1,the desulfurization rate can reach 98%.
