GB/T 8151.21-2017 Methods for chemical analysis of zinc concentrates - Part 21: Determination of thallium content - Inductance-coupled plasma mass spectrometry and Inductance-coupled plasma-atomic emission spectroscopy (AES) - provides standards for the determination of thallium content in zinc concentrates by two different methods, applicable to thallium content in the range of 0.000050% to 0.010% and 0.0050% to 0.05%. The standard details the sample processing process and the method of analysis using Inductance-coupled plasma mass spectrometry (ICP-MS) and Inductance-coupled plasma atomic emission spectroscopy (AES) (ICP-AES), providing technical support for the accurate determination of thallium content in zinc concentrates.
