| 摘 要： | 对一种全新的方法—电化学法测定COD进行了初步研究。制备出析氧超电位很大的铂基α PbO2 和 β PbO2 双镀层电极 ,并用以电解产生羟基自由基直接氧化废水中有机物。在本研究确定的条件下 ,COD标液在 0～ 30 0mg L呈良好的线性关系 ,一次测定仅需 30s。

| Abstract: | A preliminary study on electrochemical method for determining COD Cr is conducted.A dual-coated electrode is prepared,with which hydroxyl free radical can be produced by electrolysis to oxidize directly the organic matters in wastewater.A good linear relation can be obtained on conditios determined by the study with the standard solution's COD Cr being 0～300 mg/L.It takes only 30 s for measuring a sample. |

| Keywords: | COD Cr hydroxyl free readical electrode electrochemical method and monitoring of water quality |
