摘要
为了更准确地分析饮用水体中有机物的污染程度,采用燃烧氧化―非分散红外吸收法中直接法和差减法相结合的新方法测定饮用水中总有机碳(TOC),对单独使用直接法或差减法进行了优化。通过实验确定了该方法的检出限为0.12 mg/L,相对标准偏差为0.62%～1.97%,加标回收率为94%～102%,可用于测定饮用水中的总有机碳。
In order to analyze organic pollution degree in drinking water more effective, a new method of combustion oxidation nondispersive infrared absorption that direct method combine with difference subtraction was established to determinate total organic carbon in drinking water, this method has optimized the method of using one method alone. Experiments showed that the detection limits were 0.12 mg/L, the relative standard deviations were between 0.62%-1.97%, the recovery rates were between 94%-102%, which can be used for the determination of total organic carbon in drinking water.
