GB/T 20899.14-2017 "Methods for chemical analysis of gold ores, Part 14: Determination of thallium content Inductance-coupled plasma atomic emission spectroscopy (AES) and Inductance-coupled plasma Mass spectrometry" specify two methods for the determination of thallium content in gold ores, applicable to the range of 20.0 µg/g to 250.0 µg/g and 0.20 µg/g to 50.0 µg/g. The standard details the sample pretreatment methods such as acid analysis, foam enrichment and solution dissolution steps, and uses Inductance-coupled plasma technology for thallium content analysis. The standard is suitable for the accurate determination of thallium content in gold ores and provides technical support for ore analysis.
