摘要
以自制铌酸为催化剂,高压汞灯为光源,进行了光催化降解玫瑰红B的实验。讨论了铌酸的光催化机理,研究了催化剂、过氧化氢用量、降解时间等对玫瑰红B降解率的影响。玫瑰红B在降解范围内符合零级动力学方程。
The photocatalytic degradation experiment of rhodamine B was conducted,and used home-made niobic acid as catalyst,high-pressured mercury lamp as light source.Photocatalytic mechanism of niobic acid was studied.The effects of quantity of H2O2,catalyst and time on decomposition of rhodamine B were investigated.The photocatalytic degradation rate followed pseudo-zero order kinetics in the range of rhodamine B concentration.
