摘要
介绍了一种适于工业废水化学耗氧量测定的小体积加压溶弹法．通过实际样品的考查表明，新方法的变异系数不大于１．２０％，测定误差的绝对值小于６ｍｇ·１－１．该方法不仅具有测定速度快、操作简便、耗费低廉等特点，而且更易于批量样品的分析．
A COD determination method,pressurbe solution bomb with small volume solutionneeded .which is used for industrial wane water is introduced. With the characteristics of suitable for batch samples,simple operating procedures and low consumption etc.,this determination has a variance coefficient not more than 1.20% and an absolute error lower than 6mg/1-1 tested by samples.
