Determination of Ca and K in Soil Reference Material by ED-XRF
-
摘要: 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2O)含量在0.20%~3.04%之间,分析误差<0.2%,相对标准偏差<20%。Abstract: 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.
