HJ 803-2016 in English

本标准规定了测定土壤和沉积物王水提取液中12 种金属元素的电感耦合等离子体质谱法。
本标准适用于土壤和沉积物中镉（Cd）、钴（Co）、铜（Cu）、铬（Cr）、锰（Mn）、镍（Ni）、铅（Pb）、锌（Zn）、钒（V）、砷（As）、钼（Mo）、锑（Sb）共12 种金属元素的测定。若通过验证，本标准也可适用于其它金属元素的测定。

Scope

This standard specifies the inductively coupled plasma mass spectrometry method for the determination of 12 metal elements in aqua regia extracts of soil and sediments. This standard applies to cadmium (Cd), cobalt (Co), copper (Cu), chromium (Cr), manganese (Mn), nickel (Ni), lead (Pb), zinc (Zn), and vanadium in soil and sediments (V), arsenic (As), molybdenum (Mo), antimony (Sb), a total of 12 metal elements. If verified, this standard can also be applied to the determination of other metallic elements. When the sampling volume is 0.10 g and the fixed volume after digestion is 50 ml, the method detection limits and lower determination limits of the 12 metal elements are shown in Table 1.
