GB/T 13748 "Chemical Analysis Methods for Magnesium and Magnesium Alloys" defines the chemical composition of magnesium and magnesium alloys. Analysis and testing plays an important role and is widely used in many fields such as magnesium and magnesium alloy product research and development, trade settlement, chemical element comparison, etc. It provides important support for the research and development, production, and trade of magnesium and magnesium alloy products in China. GB/T 13748 includes spectrophotometry, gravimetric method, atomic absorption spectrometry, inductively coupled plasma atomic emission spectrometry, optical Various analytical methods such as direct reading spectrometry and wavelength dispersive X-ray fluorescence spectrometry are aimed at standardizing the chemical analysis that affects the performance of magnesium and magnesium alloy products. Chemical elements such as aluminum, tin, lithium, manganese, zinc, zirconium, nickel, copper, beryllium, silicon, iron, lanthanum, cerium, praseodymium, neodymium, gadolinium, yttrium, etc. After optimization and integration, it is planned to consist of the following parts. Part 1.Determination of aluminum content; Part 2.Determination of tin, beryllium, copper, nickel and titanium content - Spectrophotometric method; Part 3.Determination of lithium and silver content - Atomic absorption spectrometry; Part 4.Determination of manganese and zirconium content - Spectrophotometric method; Part 8.Determination of rare earth content; Part 9.Determination of iron and silicon content - Spectrophotometric method; Part 13.Determination of lead, calcium, potassium and sodium content - Atomic absorption spectrometry; Part 15.Determination of zinc content;- Part 18.Determination of chlorine content - Silver chloride turbidimetric method; Part 20.Determination of elemental content - Inductively coupled plasma atomic emission spectrometry; Part 21.Determination of element content - Photoelectric direct reading atomic emission spectrometry; Part 22.Determination of thorium content; Part 23.Determination of elemental content - Wavelength dispersive X-ray fluorescence spectrometry; Part 24.Determination of trace impurities by glow discharge mass spectrometry. This document gives the determination of aluminum, zinc, manganese, silicon, iron, The XRF method can simultaneously determine the content of copper, titanium, strontium, nickel, lead, zirconium, gadolinium, yttrium, cerium and neodymium in magnesium and magnesium alloy samples.
