GB/T 43753.2-2024 《Methods for chemical analysis of precious metals alloys electroplating wastewater—Part 2：Determination of zinc, manganese, chromium, cadmium, lead, iron, aluminium, nickel, copper and beryllium contents—Inductively coupled plasma-atomic emission spectrometry》 Related products

GB/T 43753.2-2024 "Methods for chemical analysis of precious metal alloy Eletroplating wastewater, Part 2: Determination of zinc, manganese, chromium, cadmium, lead, iron, aluminum, nickel, copper, beryllium content Inductance coupled plasma atomic emission spectroscopy (AES) method" provides for the use of Inductance coupled plasma atomic emission spectroscopy (AES) method for the determination of zinc, manganese, chromium, cadmium, lead, iron, aluminum, nickel, copper, beryllium content in precious metal alloy Eletroplating and electroforming wastewater. This standard applies to the determination of zinc, manganese, chromium, cadmium, lead, iron, aluminum, nickel, copper, beryllium. The mass concentration range is from 0.000 1 mg/mL to 0.100 0 mg/mL. During the determination, the sample is digested by perchloric acid after the organic matter is dissolved in a mixed acid medium. 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.
