X-荧光能谱法测定土壤标样中钙和钾研究初报

Determination of Ca and K in Soil Reference Material by EDXRF

应用Ｘ－荧光能谱仪中定量分析软件，选择适当试验条件，测定土壤标样中钙（ＣａＯ）、钾（Ｋ２Ｏ）含量。结果表明，土壤标样中钙（ＣａＯ）含量在０．０５％～３．２３％之间，分析误差＜０．２％，相对标准偏差≤２０％；钾（Ｋ２Ｏ）含量在０．２０％～３．０４％之间，分析误差＜０．２％，相对标准偏差＜２０％。

Ca and K in soil reference materials were analysed by EDXRFThe results showed that the analysis precission RSD was less than 02% for Ca and KThe analysis method was rapid and reliable
