| 摘 要： | 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。

| Abstract: | 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 simultaneously 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 deviation（RSD）was lower than 5%,The method shows the advantages of good reproducibility and better precision. |
