Effect of Nitrate and Sulfate Contamination on Degradation of Diuron via Electrochemical Advanced Oxidation in a Microreactor

摘要: The degradation of diuron, which is a toxic herbicide that causes serious environmental problem in many countries, was performed using electrochemical advanced oxidation process (EAOP) microreactor. influence nitrate and sulfate contamination on the investigated. experimental results clearly indicate both ions retard diuron degradation. Under applied current 1 mA, about 91% deionized water degraded within 100 s residence time, while achieved 79% 76% when are presented solution at concentration 50 mM, respectively. Both behave as scavenger for reactive hydroxyl radical, although other mechanisms might also involve causing this retarding effect. Nitrate ion participates new reaction pathways, does not interfere with pathway. presence shifts route from one to another.
