摘　　要：以采用溶胶-凝胶法制备固定膜Ru/TiO2光催化剂的钛网为基材,并对其施加不同的电压和电流,对活性艳红X-3B印染废水进行了光助电催化研究,讨论了阳极电流、不同电解质、pH值以及Cl-浓度对活性艳红X-3B降解效率的影响规律,并比较了光助电催化降解与光催化降解、电解处理对活性艳红降解率的差异。结果表明:相同条件下,光助电催化降解X-3B的速率明显快于单纯的电解和光催化降解速率。The light assisted electricity - catalysis of reactive brilliant red X- 3B was studied with Ti net as radical material and adopting solidified membrane Ru/TiO2 photocatalyst prepared by sol- gel method and applying varies voltage and current to it. The discussion of the anode current, different electrolytes, pH value and chloride concentration on reactive brilliant red X - 3B degradation rate and the difference of light assisted electricity - catalytic degradation with photocatalytic degradation, electrolysis treatments was compared. The result was found that light assisted electricitycatalytic degradation rate is faster than the single electricity- catalysis and photocatalysis degradation value.
