介质阻挡放电等离子体降解废水中双氯芬酸的动力学研究
Kinetic study of diclofenac degradation in aqueous solution by dielectric barrier discharge plasma
摘要
Abstract
Pharmaceuticals and personal care products(PPCPs)are frequently detected in water in recent years.In this paper,diclofenac(DCF)was selected as the target contaminant and the macro-kinetics of DCF degradation was investigated based on a plate type circulating dielectric barrier discharge(DBD)reactor.The macroscopic kinetics of DCF degradation was investigated based on the degradation experiments in a flat-plate circulating DBD reactor.The results show that the degradation of DCF in a flat plate circulating DBD reactor is consistent with primary kinetics,and the degradation rate constant is 0.175 min-1.The macro kinetic reaction constants are affected by input voltage,electrode spacing and initial concentration,and K=8.533 mol·min-1·mm3.25·W-0.75.The conversion rate of DCF in a single flow through the discharge region is affected by input power,electrode spacing and solution flow rate,and the intrinsic kinetic reaction of DCF in a DBD system is a secondary reaction.关键词
