摘要
以钛酸四丁酯为原料,用溶胶-凝胶法制备了以膨润土为载体的负载型TiO2光催化剂;采用分光光度法测试其光降解性能;讨论了影响苯酚降解的主要因素。结果表明,在pH=8.0时,光催化剂的用量为15mg/L,苯酚溶液的浓度为5mg/L时,光照时间为120min,苯酚的降解率可达98.2%。
The bentonite loaded titanium oxide photocatalyst was prepared by sol-gel method with tetrabutyl titanate as raw materials,and the phtotdegradation performance of photocatalyst was determined by spectrophotometry,and the main factors of effect on photodegradation of phenol were discussed.The degradation rate reached 98.2% when the value of pH was 8.0,the dosage of photocatalyst was 15mg/L,and the concentration of phenol was 5mg/L,with the illumination time of 120min.
