摘要

电化学去除污水COD是一种高效绿色快速的方法;在电化学法处理某油田含聚采油污水中,产生活性中间体H_2O_2间接氧化去除COD。Ti与5-Br-PADAP及H_2O_2在p H=1~1.5时能形成稳定的三元络合物,该三元显色体系在561nm附近明显的吸收峰,H_2O_2浓度在0.2~10μmol/L的范围内遵从Beer-Lambert Law,因此可建立起用分光光度法检测电化学法处理污水过程中微量活性中间体H_2O_2的方法。该方法简便、快速、重现性好、费用低,灵敏度高,在测定电化学过程中微量活性中间体H_2O_2的实际应用中获得了满意效果。
Electrochemistry is an efficient,fast and green method for the COD removal of sewage.The electrochemical treatment process of sewage containing polymer in an oilfield produces some reactive intermediates such as H_2O_2 which can remove COD by indirect oxidation.Ti and 5-Br-PADAP with H_2O_2 can form a stable colored ternary complex at pH = 1 ~ 1.5,and there is an obvious absorption peak of this ternary color system at about 561 nm.Within the range of 0.2~10 μmol/L H_2O_2 the Beer-Lambert Law is hold,therefore a method of Spectrophotometry can be established for determination of trace reactive intermediates about H_2O_2 in the process of electrochemical treatment of sewage.The method is easy,rapid,reproducible,cheap and high sensitive,and it obtains satisfying results in practical applications.
