GB/T 43753.1-2024 "Methods for chemical analysis of precious metal alloys Eletroplating wastewater, Part 1: Determination of gold, silver, platinum, palladium, iridium content Inductance coupled plasma atomic emission spectroscopy (AES) method" The method for the determination of gold, silver, platinum, palladium and iridium content in precious metal alloys Eletroplating and electroforming wastewater using Inductance coupled plasma atomic emission spectroscopy (AES) method is specified. This standard applies to the determination of gold, silver, platinum, palladium and iridium in the mass concentration range of 0.000 1 mg/mL to 0.100 0 mg/mL. During the determination process, the sample is digested by perchloric acid, the organic matter is dissolved in a mixed acid medium, and the content of each element is determined by Inductance Coupled Plasma Atomic EmissionSpectrometer. This document refers to the provisions of GB/T 6682 on the specifications and test methods for analytical laboratory water.
