摘要
采用国产石墨消解仪消解土壤标样,经原子吸收分光光谱测定土壤总铬。利用建立的方法检测了土壤标样中Cr元素含量。统计实验数据显示,土壤标样的测定值没有偏离其保证值,三个土壤标样的标准偏差范围：0.22-0.69,相对标准偏差范围：0.32%-2.33%,可见用本方法消解测定土壤中的铬元素可行。
The soil samples were digested by domestic graphite digestion apparatus, and the total Cr element which content in the soil was determined by atomic absorption spectroscopy. The Cr element content in soil samples was detected by the established method. Statistical experimental data show that the measured values of soil samples did not deviate from the guarantee value, three soil samples of the standard deviation range： 0.22-0.69, the relative standard deviation range： 0.32%-2.33%, so the method of digestion for determination of Cr element in soil is feasible.
