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

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
