摘要
以钛极板为阴极、钌铱电极为阳极,对聚丙烯酰胺(PAM)废水进行电催化氧化降解,探讨了电流密度、极板间距、PAM初始浓度、初始pH值等因素对PAM降解率的影响。确定最佳降解条件为:电流密度30 mA·cm^(-2)、极板间距3 cm、初始pH值6,在此条件下,对1 L PAM初始浓度为500 mg·L^(-1)的PAM模拟废水进行电催化氧化降解,PAM降解率达90.27%,降解效果较好。
Using titanium plate as a cathode,and ruthenium-iridium electrode as an anode,we performed the electrocatalytic oxidation degradation of polyacrylamide(PAM)wastewater,and investigated the effects of current density,plate spacing,initial concentration of PAM,and initial pH value on the degradation rate of PAM.The optimal degradation conditions can be determined as follows:the current density of 30 mA·cm^(-2),the plate spacing of 3 cm,and the initial pH value of 6.Under above conditions,the degradation rate of PAM in 1 L PAM simulated wastewater with the initial concentration of PAM of 500 mg·L^(-1) can reach 90.27%,indicating that the degradation effect is good.
