摘　　要：光催化降解技术用于治理环境有机污染物具有安全清洁、廉价高效的优点。光催化剂是光催化技术的核心,配位化合物作为新型晶态有机-无机杂化材料,具有种类丰富、结构可控、比表面积大等独特的物理化学性质。本文以均苯三甲酸-镍配位化合物(BTC-Ni)为光催化剂,以苯酚溶液模拟废水,研究了不同苯酚初始浓度、BTC-Ni投加量、与H_(2)O_(2)合用情况下对苯酚光催化降解性能的影响。结果表明,BTC-Ni与H_(2)O_(2)合用对20 mg/L苯酚溶液在100 min时达到了98%降解率,符合一级反应动力学方程,反应速率常数为0.0303 min^(-1)。Photocatalytic degradation technology for the treatment of environmental organic pollutants has the advantages of safety,cleanness,low cost and high efficiency.Photocatalyst is the core of photocatalytic technology.As a new crystalline organic-inorganic hybrid material,coordination compounds have unique physical and chemical properties such as rich species,controllable structure and large specific surface area.In this paper,1,3,5-benzenetricarboxylic acid nickel coordination compound(BTC-Ni)was used as photocatalyst,taking phenol as simulated wastewater,the effects of different initial concentration of phenol,dosage of BTC Ni and combination with H_(2)O_(2)on the photocatalytic degradation of phenol were studied.The results showed that the degradation rate of 20 mg/L phenol solution by BTC-Ni combined with H_(2)O_(2)reached 98%in 100 min,conformed to the first-order reaction kinetic equation,and the reaction rate constant was 0.0303 min^(-1).
