摘要
本文介绍了以低压聚乙烯垫底、镶边、粉末直接压片、X荧光谱定量测定土壤中常量元素的方法。用逐步回归法选择影响元素,并以散射内标与经验系数相结合校正基体效应,同时对“经验系数法”和“基本参数与经验系数结合法”进行了比较。
The method has been described on the determination of major elements in soil using pressed powder pellets rimmed and backed with low pressure polyethlene by XRF. In the correction for matrix effects, the stepwise regression method was used to select influence elements and the matrix effects were corrected with the combination of empirical correction method and scatter internal method. The results obtained by empirical coefficient method were compared with the method based on fundamental parameter and empirical coefficient methods.
