本文介绍在文献基础上用高温氧化红外分析测定江水中总有机碳(TOC)。特点是①既具有分别测定水中总碳与无机碳,从二者差值求出总有机碳的高低温炉的流程;又具有提供“无碳”空气流,可先 This article describes the determination of total organic carbon (TOC) in river water using high temperature oxidation infrared analysis based on literature. The characteristic is that both the process of determining high and low temperature furnaces for determining the total organic carbon in the total carbon and the inorganic carbon in the water and the difference between the two is also provided with a “carbon-free” air flow,
