2、行了表征。此外,以所合成的掺杂材料为催化剂,在紫外灯下照射lOOmin,研究了孔雀石绿溶液的光催化降解的反应。实验研究结果表明,两种杂多酸盐掺杂材料的光降解的最佳条件一致,当孔雀石绿溶液以5mg/L为最初的浓度、加入O.O8g的合成的催化剂、pH=2时,催化脱色效果最佳。此时,当催化剂为K8[Zn(H2O)W!!CoO39]/PANI时,孔雀石绿染料液脱色效果是85.30%;当催化剂为K8[Ni(H2O)WiiCoO39]/PANI时,孔雀石绿染料液脱色率是89.92%;当催化剂为K8[Zn(H2O)WnCoO39]时,孔雀石绿溶液脱色率为48.7
3、3%;当催化剂为K8[Ni(H2O)W11CoO39]时,孔雀石绿溶液脱色率为55.63%;当没有催化剂时,孔雀石绿口动降解溶液脱色率22.97%0PANI和杂多酸盐掺杂后所制备出的催化剂具有非常好催化活性。关键词:杂多酸盐;Keggin;聚苯胺;掺杂;光催化;孔雀石绿;降解AbstractInthiswork,TwoheteropolyacidsaltsaresynthesizedbythedirectmethodKg[Ni(H20)W11COO39],Ks[Zn(H2O)W11COO39]andthestructureofeverysaltis
