1 Scope

This part of YS/T 1116 specifies the method for the determination of copper, lead and bismuth in tin anodic mud. This part is applicable to the determination of copper content, lead content and bismuth content in tin anode mud. The measurement range is shown in Table 1. Table 1 Measurement range Element Cu Pb Bi Measurement range /% 1.00 ~ 5.00 0.50 ~ 5.00 1.00 ~ 5.00

2 method summary

Samples with hydrochloric acid, nitric acid, perchloric acid decomposition, hydrobromic acid volatilization to remove tin and antimony. In dilute hydrochloric acid medium, use air-acetylene flame Atomic Absorption Spectrometer at the corresponding wavelength (see Table 2), measure the absorbance of each element, according to the standard curve method to calculate its content. Table 2 Determination of wavelength Element Cu Pb Bi Wavelength/nm 324.7 283.3 223.1

3 reagent

Unless otherwise stated, only the reagents and secondary water confirmed to be analytical were used in the analysis. 3.1 Hydrochloric acid (ρ1.19g/mL). 3.2 nitric acid (ρ1.42g/mL). 3.3 hydrobromic acid (ρ 1.49 g/mL). 3.4 perchloric acid (ρ1.67g/mL). 3.5 Hydrochloric acid (1 1). 3.6 nitric acid (1 1). 3.7 copper standard storage solution. Weigh 1.0000g metal copper (wCu ≥ 99.99%) in 400mL beaker, add 50mL nitric acid (3.6), slightly hot to dissolve completely, remove the cooling, into the 1000mL volumetric flask, add 50mL nitric acid (3.6), diluted with water to the mark, Mix well. 1 mL of this solution contains 1 mg of copper. 3.8 lead standard storage solution. Weigh 1.0000g metal lead (wPb ≥ 99.99%) in 400mL beaker, add 50mL nitric acid (3.6), slightly hot to dissolve completely, remove the cooling, into the 1000mL volumetric flask, add 50mL nitric acid (3.6), diluted with water to the mark, Mix well. This solution 1mL containing 1mg of lead. 3.9 bismuth standard storage solution. weighed 1.0000g metal bismuth (wBi ≥ 99.99%) in 400mL beaker, add 50mL nitric acid ......
