GB/T 6150.2-2022 《Methods for chemical analysis of tungsten concentrates—Part 2: Determination of tin content—Potassium iodate titrimetry and inductively coupled plasma atomic emission spectrometry》 Related products
This standard specifies methods for the determination of tin content in tungsten concentrates using the potassium iodate Titrimetric method and the Inductance coupled plasma atomic emission spectroscopy (AES) method. The potassium iodate Titrimetric method is suitable for the determination of tin content in samples with a tin content of 1.00% to 20.00%, while the Inductance coupled plasma atomic emission spectroscopy (AES) method is suitable for the determination of samples with a tin content of 0.010% to 2.00%. For the part of the measurement range that overlaps, the Inductance coupled plasma method is used as the arbitration method. The standard details the experimental operation steps and the use of related reagents.
