GB/T 1819.4-2004 《Methodsfor chemical analysis of tin concentrates--Determination of lead content--Flameatomic absorption spectrometric method and EDTA titrimetric method》 Related products
This standard specifies the determination method of lead content in tin concentrate, which is applicable to the determination of lead content in the range of 0.005% to 5.00%. Absorbance of lead is determined by flame atomic absorption spectroscopy (AAS). During operation, the sample needs to be analyzed with muriatic acid and nitric acid, and the measurement of lead Absorbance in air-acetylene flame. In addition, the EDTA Titrimetric method can also be used as an auxiliary determination method. The standard describes in detail the steps of reagent preparation, instrument requirements, sample preparation, etc., and provides a standardized analysis process to ensure the accuracy and reliability of the measurement results.
