摘要
以分子筛MCM-48负载磷钨杂多酸制备光催化剂H3PW12O40/MCM-48,考察其在光照条件下对模拟染料废水甲基橙溶液的光催化脱色性能。结果表明,当H3PW12O40/MCM-48催化剂用量为6.0 g/L,甲基橙的初始含量为7.0 mg/L,光照5.5 h时,甲基橙溶液的脱色率可达84.53%。
The H3PW12O40/MCM-48 photocatalyst was prepared by loading phosphotungstic acid on MCM-48 zeolite,and the effects of conditions on the degradation of methyl orange solution under illumination were investigated.The results showed that the degradation of methyl orange solution reached 84.53% under the conditions of methyl orange concentration 7.0 mg/L,H3PW12O40/MCM-48 dosage 6.0 g/L and illumination time 5.5 h.
