利用化学耗氧量测定仪测定水体中的腐殖酸

Determination of the Humic Acid in Water by COD Detector

建立了利用化学耗氧量测定仪测定水体中腐殖酸的新方法.本方法简便、快捷,腐殖酸与化学耗氧量(COD)可同时进行测定.线性相关系数(r)为0.9907.相对标准偏差(RSD%)为1.36.

A new method was established using COD detector to detemine the humic acid in water. This method is very handy and fast and can be finished in process of COD detennination. Regression equation is Y = 2.65X - 2.94, Correlation coefficient is 0.9907, RSD% is 1.36.
