本文提出用铝环-双层压片法制片,经验系数法校正吸收-增强效应,对少量土壤样品中的常量和微量元素进行了定量测定。取样量为500 mg,制样与测量精确度好于5%,用本法对标样的分析表明,分析值与推荐值基本一致,本法具有简单、快速、成本低的特点,适用于少量样品的分析。 In this paper, the alicyclic double-layer tablet method was used to prepare and the absorption coefficient-enhancing effect was corrected by the empirical coefficient method. The contents of trace elements and trace elements in a few soil samples were determined quantitatively. Sampling amount of 500 mg, sample preparation and measurement accuracy of better than 5%, the method of analysis of standard samples showed that the analysis of the value and the recommended value is basically the same, the method has the characteristics of simple, fast, low cost, suitable for a small amount Sample analysis.
