摘要
通过优化CODcr的分析条件和步骤并选择合适的试剂,建立了一种基于HJ/T399-2007检测高含量Cl-低浓度CODcr样品的方法。测定结果的相对标准偏差为1.8～3.5(n=5),相对误差为0.9～2.9。方法具有前处理程序简单、分析时间短、不需要另配试剂的特点,方法的精确度满足国家规定的要求。
The determination method of high chloride content and low CODer samples was established based on HJ/T 399 - 2007 by optimizing determination conditions and steps, selecting suitable reagent. The relative standard deviation were 1.8% to 3.5% （ n = 5） , and the relative error were 0.9% to 2.9%. This method was simple, quick without other reagents. The results of determination can fully meet the national requirements.
