Description

technical field [0001] The invention relates to the technical field of alloy composition analysis, in particular to a method for measuring tin, antimony, arsenic, bismuth, copper, cadmium, calcium and silver in lead alloys by using wavelength dispersive X-ray fluorescence spectrometry. Background technique [0002] Due to the characteristics of high density, low melting point, good corrosion resistance and radiation protection, lead and lead alloys have a wide range of applications and cannot be replaced by other metals. Lead alloys are used in electrolytic zinc, electrolytic copper and battery industries. As anodes in hydrometallurgical processes, they have the advantages of high hardness, good mechanical properties, excellent casting performance, long service life, and simple production processes. Lead alloys are not easily penetrated by X and gamma rays, and can be used as protective materials for radioactive work. [0003] The elements in lead and lead alloys are mainly...
