Scope
HG/T 4550.2-2013 is the English-translated version of 废弃化学品中镉的测定 第2部分：火焰原子吸收分光光度法.
Part 2 of the HG/T 4550 series, HG/T 4550.2-2013 is a recommended chemical industry standard of China covering the determination of cadmium in waste chemicals by flame atomic absorption spectrophotometry. It explains the principle of the technique and then the reagents and materials, the instruments and equipment, the handling of the sample, the steps of the analysis and the calculation of results. The method is intended for laboratories measuring the cadmium content of discarded chemical products, where the flame technique suits the higher concentration range. GB/T 6682-2008, HG/T 3696.2 and HG/T 3696.3 are cited. Issued on 17 October 2013, it has applied since 1 March 2014.
