Atomic Absorption Spectrometry is an analytical technique used to determine the content of a specific element in a sample. The specific operation steps include proper pretreatment of the electrolyte sample, and then determination by atomic absorption spectrometer. The instrument irradiates the sample with a light source of a specific wavelength, so that the atomic absorption spectrum of the element to be measured produces a characteristic absorption peak, so that the concentration of the element can be calculated according to the absorption intensity. This method has the advantages of high sensitivity, good selectivity and simple operation, and is widely used in chemical analysis, materials science, environmental monitoring and other fields. This paper focuses on the method of atomic absorption spectrometry for the determination of the content of Sn Ag Cu element in the electrolyte. The method adopts East-West Analysis AA-7020 Atomic Absorption Spectrometer, which can be used for reference by relevant personnel. Attachment Download
