This section GB/T 10574 Part 10.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 10574.10-2003 "chemical analysis of tin-lead solder Part 10. Determination of cadmium," This section
GB/T 10574.10-2003 compared to the main technical changes are as follows.
--- Increasing the normative references;
--- 1 Range Method 1 The measurement range is changed from "0.00002% to 0.0050%" to "0.00005% to 0.0050%";
---.2003 edition 5.3.1 "added 0.1mL ~ 2.0mL hydrochloric acid (3.1)" to "add 2mL hydrochloric acid (3.2.1)";
--- Buffer solution from acetic acid - sodium acetate solution was modified to hexamethylenetetramine solution (see 4.2.7);
--- Precision from "allowable error" to "repeatability and reproducibility" (see 3.7,4.6);
--- Calibration Na2EDTA standard titration solution from cadmium standard solution to lead standard solution (see 4.2.11).

3 Method 1 Flame atomic absorption spectrometry
3.1 Method summary
After the sample was dissolved in hydrochloric acid and nitric acid, sulfuric acid was added to precipitate most of the lead. In the presence of a small amount of sulfuric acid, hydrochloric acid - hydrobromide volatile addition
Tin, antimony, the use of air - acetylene flame, atomic absorption spectrometer at a wavelength of 228.8nm Department, measuring the absorbance of cadmium.
3.2 Reagents
Unless otherwise stated, only reagents identified as analytically pure and distilled or deionized water or rather pure water were used in the analysis.
3.2.1 Hydrochloric acid (p = 1.19 g/mL).
3.2.2 Nitric acid (p = 1.42 g/mL).
3.2.3 hydrobromic acid (p = 1.48 g/mL).
3.2.4 hydrochloric acid - hydrobromic acid mixed acid hydrochloric acid (3.2.1) and hydrobromic acid (3.2.3) and other volume mixing.
3.2.5 Hydrochloric acid (1 1).
3.2.6 Hydrochloric acid (5 95).
3.2.7 Nitric acid (1 2).
3.2.8 Sulfuric acid (1 1).
3.2.9 Cadmium standard storage solution Weigh 0.5000g metal cadmium (wCd ≥ 99.99%) in.200mL beaker, add 20mL nitric acid
(3.2.7), cover the watch glass, slightly warm to completely dissolve, wash the watch glass and cup wall with water and cool. Into a 500mL volumetric flask, add
25mL hydrochloric acid (3.2.1), diluted with water to the mark, mix well. 1mL of this solution contains 1mg of cadmium.
3.2.10 Cadmium standard solution A. Pipette 25.00mL standard solution of cadmium (3.2.9) in 250mL volumetric flask, with hydrochloric acid (3.2.6) thin
Release to the mark, mix well. 1 mL of this solution contains 100 μg of cadmium.
3.2.11 Cadmium standard solution B. Pipette 25.00mL of cadmium standard solution A (3.2.10) in 250mL volumetric flask, diluted with hydrochloric acid (3.2.6)
