摘要
环境土壤中的TOC(总有机碳)含量是反应土壤有机污染的一个重要指标。文章描述了应用总有机碳测定仪和固体进样装置对土壤中TOC含量的测定方法,建立TC(总碳)和IC(无机碳)测定标准曲线,利用差减法计算出TOC含量。实验结果表明,利用该方法建立的标准曲线线性良好,多次测定样品的相对标准偏差较小,该方法精密度、准确度较高。
The content of TOC(total organic carbon)in environmental soil is an important indicator of soil organic pollution.This paper describes the application of total organic carbon analyzer and solid sampling device for determination of TOC content in soil and establishes TC(total carbon)and IC(inorganic carbon)standard curve to calculate the content of TOC.The experimental results showed that the standard curve established by this method is with good linear relation.Even after repeatedly determination the relative standard deviation of samples was smaller.This method is of high accuracy.
