非色散红外吸收法测定地表水和废水中的总有机碳

Determination of Total Organic Carbon in Surface Water and Waste Water Samples by Nondispersive Infrared Absorption Spectrometry

用燃烧氧化 -非色散红外吸收法测定了杭州市辖区内的地表水、污水处理厂排水和不同行业工业废水中的总有机碳 (TOC)。结果表明 ,本法检出限为 0 .3mg/ L ,对于 TOC浓度在 6 .1— 12 0 mg/ L范围内水样的测定 ,相对标准偏差在 1.3%— 10 %之间。

The total organic carbon(TOC) in surface water,sewage effluent and different kinds of industrial wastewater of Hangzhou,was determined by nondispersive infrared absorption spectrometry with combustion oxidation.The detection limit is 0.3mg/L and the relative standard deviations are in the range of 1.3%-10% for the concentration range of 6.1-120mg/L of TOC.
