Scope
GB/T 14353.20-2019 is the English-translated version of 铜矿石、铅矿石和锌矿石化学分析方法 第20部分：铼量测定 电感耦合等离子体质谱法.
GB/T 14353.20-2019 is Part 20 of the Chinese national series of methods for the chemical analysis of copper ores, lead ores and zinc ores, and specifies the determination of rhenium content in copper ores or polymetallic ores by inductively coupled plasma mass spectrometry (ICP-MS).
It gives two sample pretreatments: Method 1, sintering with magnesium oxide at 700 °C followed by hot-water leaching, and Method 2, closed-vessel digestion with nitric and hydrofluoric acids at 190 °C with removal of matrix cations on a cation exchange resin; both use rhodium as internal standard, have a detection limit of 0.004 µg/g and cover 0.01 µg/g to 15.0 µg/g.
For each method it sets out the reagents and standard solutions, instruments, sample preparation, blank and verification tests, calibration series, measurement and calculation of results, followed by interlaboratory precision data and requirements for quality assurance and control.
It is a new part of the series and does not replace an earlier edition. Issued on 18 October 2019, in force since 1 May 2020. Classification: ICS 73.060, CCS D40. The document runs to 11 pages, delivered complete in English translation.
