摘要
以Fe_3O_4/TiO_2为催化材料,分别研究了催化剂在不同催化剂的投加量、不同pH以及不同光照条件下对罗丹明的光催化效果,并用表观速率常数k评价催化剂的光催化活性。研究表明:罗丹明B的光催化反应为一级动力学反应,且在Fe_3O_4/TiO_2复合物投加量在20 g·L^(-1)、pH=6、紫外光照射的条件下降解效率最高。
Taking the Fe_3O_4/TiO_2 as catalytic material, catalyst was studied in the different catalyst dosing quantity under different light conditions, different pH value and photocatalytic effect of rhodamine, and the apparent rate constant k evaluation of photocatalytic activity of the catalyst. Research showed that the photocatalytic reaction of rhodamine B for the first order kinetics reaction, and in the Fe_3O_4/TiO_2 compound additive quantity in 20 g·L^（-1）, pH=6, uv irradiation in the most efficient.
