鸭绿江丹东段水体TOC与高锰酸盐指数相关性及应用探讨

Discussion on the Relationship between TOC and Permanganate Index in Surface of Yalujiang River(Dandong Part)

通过对2007年~2009年鸭绿江丹东段地表水中TOC和高锰酸盐指数进行枯、丰、平三个水期109组数据同步监测的结果表明,两者之间存在密切的相关关系,经一元线性回归得出三个水期的回归方程。经相关系数显著水平检验,表明在99.9%的置信水平下,TOC和高锰酸盐指数线性相关非常显著。

Total organic carbon（TOC） and Permanganate index in surface of Yalujiang river（Dandong part） were monitored from 2007~2009.The result from 109 groups data showed that a kind of correlativity existed between TOC and Permanganate Index.The paper educed the regression equation by means of one dimensional regression analysis.The test of significance showed that under the 99.9% confidence level,the linear correlation of TOC and Permanganate index was notable.
