1 Scope

YS/T 556 This section specifies the determination of antimony concentrates cadmium content. This section applies to the determination of antimony concentrates cadmium content. Determination range of 0.0010% to 0.050%.

2 Method summary

A specimen in a hydrochloric acid, nitric acid, perchloric acid dissolved, in addition to volatilization of antimony hydrobromic, hydrochloric acid (119) media, using air - acetylene flame, Atomic absorption spectrometer wavelength 228.8nm measured absorbance cadmium.

3 Reagents

Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity. 3.1 ammonium hydrogen fluoride. 3.2 hydrochloric acid (ρ = 1.19g/mL). 3.3 nitric acid (ρ = 1.42g/mL). 3.4 hydrobromide (ρ = 1.38g/mL). 3.5 perchloric acid (ρ = 1.68g/mL). 3.6 hydrochloride (11). 3.7 nitric acid (11). 3.8 cadmium standard stock solution. Weigh 1.0000g metal cadmium (wCd≥99.99%) in 250mL beaker, add 40mL of nitric acid (11), dissolved by heating, boiling rid of nitrogen oxides, remove the cooled to room temperature and transferred to 1000mL volumetric flask, dilute to the mark, Mix well. This solution 1mL containing cadmium 1.000mg. 3.9 Cadmium standard solution. Pipette 5.00mL cadmium standard stock solution (3.8) in 500mL volumetric flask, was added 20mL of hydrochloric acid (3.6), Dilute with water to volume, and mix. This solution 1mL containing cadmium 10μg.

4 Instrument

Atomic absorption spectrometer, with a cadmium hollow cathode lamp. Under optimum working conditions for those who can reach the following indicators can be used. --- Characteristic concentration. the test solution and measurement matrix consistent solution, characteristic concentration of cadmium should be less than 0.014μg/mL. --- Linear curve. The curve is divided into five sections according to concentration, absorbance difference between the highest and the lowest section of the absorbance difference between segments Ratio of not less than 0.85. --- Precision. measure 10 times the absorbance of the highest concentration of the standard solution, the standard deviation should not exceed 1% of the average absorbance; with The lowest concentration standard solution (not a "zero" standard solution) absorbance measured 10 times, and the standard deviation should not exceed the standard maximum concentration ......
