摘　　要：利用总有机碳分析仪(total organic carbon analyzer,TOC)对有机物的氧化分解能力与离子色谱仪(ion chromatograph,IC)的阴离子检测功能,提出了一种仪器联用的方法(TOC-IC)。实验结果表明,采用紫外光氧化-电导检测法的总有机碳分析仪,测得的TOCi指标能够准确地反映出有机物的污染程度,与离子色谱仪联用还可以进一步获得有机物中杂原子的种类及含量。将该联用方法在火电厂中进行应用,能够快速、准确地查找出有机污染物的来源,解决水汽循环系统中有机物污染问题,值得电力行业推广。Based on the organic oxidative decomposition ability of total carbon analyzer and anion detection function of ion chromatograph(IC),this paper proposes a combined detection method of total organic carbon-ion chromatograph(TOC-IC).The experimental results showed that the TOCi index measured by the TOC analyzer with UV photooxidation-conductance detection method can accurately reflect the pollution degree of organic matter,and the type and content of heteroatoms in organic matter can be further obtained by combining with ion chromatograph.The application of the proposed method in thermal power plants can help find out the source of organic pollutants quickly and accurately,and solve the problem of organic pollution in water vapor circulation system,which is worthy of promotion in electric power industry.
