GB/T 8151.20-2012 《Methods for chemical analysis of zinc concentrates - Part 20：Determination of copper,lead,iron,arsenic,cadmium antimony, calcium,magnesium contents - Inductively coupled plasma atomic emission spectrometry》 Related products

GB/T 8151.20-2012 standard specifies the determination method of copper, lead, iron, arsenic, cadmium, antimony, calcium and mg in zinc concentrate, using Inductance Coupled Plasma Atomic Emission Spectroscopy (AES) method (ICP-AES). The sample is first analyzed with nitric acid, muriatic acid, hydrofluoric acid and perchloric acid, and then in 5% muriatic acid medium, the content of each element is determined by selecting the emission intensity of a specific wavelength. The standard method includes the specifications of the reagents and the preparation requirements of the standard solution to ensure the accuracy and Reliability of the determination. This method is suitable for the quantitative analysis of various elements in zinc concentrate.
