Water quality — Determination of chromium(VI) and chromium(III) in water — Method using liquid chromatography with inductively coupled plasma mass spectrometry (LC-ICP-MS) after chelating pretreatment 水质水中铬(VI)和铬(III)的测定螯合预处理后液相色谱-电感耦合等离子体质谱法(LC-ICP-MS)
发布日期: 2024-02-22
本文件规定了螯合预处理后,通过液相色谱电感耦合等离子体质谱(LC-ICP-MS)测定水中六价铬【Cr(VI)】和三价铬【Cr(III)】的方法。 本方法适用于废水、地表水、地下水或饮用水中溶解的Cr(Ⅵ)和Cr(Ⅲ)的测定,从0、20?微克/升至500?μ g/l每种化合物的铬(Cr)质量。可以在适当稀释样品后分析含有浓度高于工作范围的Cr的样品。

This document specifies a method for the determination of hexavalent chromium [Cr(VI)] and trivalent chromium [Cr(III)] in water by liquid chromatography with inductively coupled plasma mass spectrometry (LC-ICP-MS) after chelating pretreatment.

This method is applicable to the determination of Cr(VI) and Cr(III) dissolved in wastewater, surface water, groundwater, or drinking water from 0,20 μg/l to 500 μg/l of each compound as chromium (Cr) mass. Samples containing Cr at concentrations higher than the working range can be analysed following appropriate dilution of the sample.
