摘要
通过选择一定的仪器使用条件及样品预处理方法,利用燃烧氧化-非分散红外吸收法对生活污水、工业废水中TOC进行测定,方法的检出限为0.5mg/L,RSD为4.4%,加标回收率在91.0%～102%。本方法操作简单、快速,成本较低,灵敏度完全能满足废水中TOC项目的监测要求。
In this paper, using definite apparatus condition and sample pretreatment method, TOC is determinated in sewage and waste water by nondispersive infrared absorption method, the detection limit is 05mg/L, RSD is 44%, the recovery of added standard is between 910%～102%, this method is simple and rapid, the cost is low, the sensitivity can reach the require of TOC monitoring in waste water entirely
