1 范围
本文件描述了测定土壤中22 种元素的酸溶﹘电感耦合等离子体质谱法。
本文件适用于经过均﹘化后的土壤中锂（Li）、铍（Be）、钪（Sc）、钒（V）、铬（Cr）、锰（Mn）、
钴（Co）、镍（Ni）、铜（Cu）、锌（Zn）、砷（As）、锶（Sr）、钼（Mo）、镉（Cd）、锑（Sb）、
钡（Ba）、钨（W）、铊（Tl）、铅（Pb）、铋（Bi）、钍（Th）和铀（U）各元素总量的测定。
2 规范性引用文件
下列文件中的内容通过文中的规范性引用而构成本文件必不可少的条款。其中，注日期的引用文
件，仅该日期对应的版本适用于本文件；不注日期的引用文件，其最新版本（包括所有的修改单）适用
于本文件。
GB/T 33087 仪器分析用高纯水规格及试验方法
GB/T 36197 土壤质量 土壤采样技术指南
3 术语和定义
本文件没有需要界定的术语和定义。
4 方法原理
采用氢氟酸﹘硝酸﹘高氯酸﹘盐酸体系将土壤样品分解，使目标元素转移至待测溶液中。采用电感耦合
等离子体质谱法进行检测，根据元素的质谱图或者特征离子进行定性，内标法定量。
5 试剂和材料
5.1 除非另有说明，实验用水应符合GB/T 33087 高纯水的相关要求。
5.2 硝酸：ρ（HNO3）=1.42 g/mL，优级纯。
5.3 盐酸：ρ（HCl）=1.19 g/mL，优级纯。
5.4 氢氟酸：ρ（HF）=1.15 g/mL，优级纯。
5.5 高氯酸：ρ（HClO4）=1.68 g/mL，优级纯
