Scope
GB/T 42273-2022 is the English-translated version of 锆化合物化学分析方法 钙、铪、钛、钠、铁、铬、镉、锌、锰、铜、镍、铅含量的测定 电感耦合等离子体原子发射光谱法.
GB/T 42273-2022 is the Chinese chemical analysis method for twelve elements in zirconium compounds by inductively coupled plasma atomic emission spectrometry.
Clause 1 states that it describes the determination of calcium, hafnium, titanium, sodium, iron, chromium, cadmium, zinc, manganese, copper, nickel and lead, and that it applies to the quantitative determination of those elements in zirconium oxychloride, zirconium carbonate, zirconium sulphate and zirconium hydroxide, with the measuring range set out in Table 1: a mass fraction of 0.100 to 2.000 for hafnium and of 0.0005 to 0.050 for each of the other eleven.
Clause 4 dissolves the sample in hydrochloric acid and measures it in a dilute hydrochloric acid medium. It quotes GB/T 8170 for rounding and limit values and GB/T 17433 for analytical terms. Issued on 30 December 2022, it has applied since 1 April 2023.
