超声辐照技术降解水中有机污染物,其降解效率的评价需要简单、快捷和精确的分析方法.为此研究了6种优先控制酚类污染物的 HPLC分离及定量分析方法,方法的定量范围为 0.4-100mg/L,检测限介于 0.34-0.79ng/U L 4一氯酚的超声降解实验表明,随着反应溶液中个氯酚初始浓度的降低,降解效率明显提高,因此该方法适用于超声降解过程中酚类污染物的跟踪测定。 The degradation of organic pollutants in water by ultrasonic irradiation technology requires simple, rapid and accurate method for the analysis of degradation efficiency.Therefore, the methods of HPLC separation and quantitative analysis of six kinds of priority control phenolic pollutants were studied.The quantitative range of the method is 0.4-100mg / L, the limit of detection ranged from 0.34-0.79ng / UL 4 Degradation of monochlorophenol showed that with the decrease of initial concentration of PCP in the reaction solution, the degradation efficiency was significantly improved. Therefore, this method is suitable for ultrasonography Trace determination of phenolic pollutants during degradation.
