高级氧化技术在水质总磷检测中的应用

Application of Advanced Oxidation Process to Detection of Total Phosphorus in Water

为了克服传统方法对水体总磷含量测定中的氧化消解技术具有污染严重、繁琐、费时费力、氧化能力不足且有选择性氧化等问题,提出了组合高级氧化法,该方法具有操作简单、消解速度快、无需添加化学试剂、无二次污染等优点.通过试验分析对比,用该方法对水样总磷氧化消解完全、稳定,测量结果与合肥市环保局测量结果基本一致,对于总磷在线监测系统中的应用具有良好的实用价值.

The traditional national method because it caused serious pollution, wasted for the detection of total phosphorus in water was problematic time and energy, and had insufficient and selective oxidation. The combined advanced oxidation process proposed has more advantages because of simple operation,fast digestion, and lack of chemical reagents and secondary pollution. The experimental results show that the total phosphorus in water samples is oxidized completely and stably by this method. The test results are consistent with the results obtained by the Environmental Protection Bureau of Hefei. Thus the method is of good practical value to the online water quality monitoring system.
