建立了总有机碳（TOC）分析仪测定土壤中 TOC 的方法，绘制了总碳（TC）和无机碳（IC）的标准曲线。在此条件下，通过连续测定标准样品（GSS -16）验证了该方法的精密度，同时测试了实际土壤样品中 TOC 的含量。结果显示二者曲线相关系数 r ＝0．9998，表明该方法的标准曲线具有良好的相关线性。实验室内相对标准偏差RSD ＜0．05，充分体现了 TOC 分析仪法精密度高，结果重现性好等优点。

A method was developed for determination of total organic carbon in soil by TOC analyzer . TC and IC calibration curve were established .Under the optimal conditions ,the method was used for simul-taneously precision determination of national standard matter (GSS-16) and total organic carbon in soil . The results showed that the calibration curve of TC and IC were 99.98% and the relative standard devia-tion(RSD) was lower than 5% ,The method shows the advantages of good reproducibility and better preci-sion .
