Methods for chemical analysis of zinc concentrates
Part 5. Determination of lead content
Flame Atomic Absorption Spectrometry
1 Scope
This section GB/T 8151 provisions of the determination of zinc concentrate lead content.
This section applies to the determination of zinc concentrate - Determination of lead content range. 0.50% - 6.00%.
2 Method summary
Samples with hydrochloric acid, nitric acid dissolved in dilute nitric acid medium, atomic absorption spectrometer at a wavelength of 283.3nm, air - acetylene flame,
Measuring the absorbance of lead.
3 Reagents
Unless otherwise indicated in the analysis using only recognized as analytical reagent and distilled or deionized water or equivalent purity.
3.1 hydrochloride (ρ1.19g/mL).
Nitrate 3.2 (ρ1.42g/mL).
3.3 nitric acid (11).
3.4 Lead standard solution. Weigh 0.4000g metallic lead (wPb≥99.99%) in 250mL beaker, add 20mL of nitric acid (3.3) cover
Table dish, heated until completely dissolved, to remove nitrogen oxides boil, cooled to room temperature. Transferred 1000mL volumetric flask and dilute to the mark with water, mix
Uniform. This solution 1mL containing 400μg lead.
4 Instrument
Atomic absorption spectrometer, with a lead hollow cathode lamp.
Under instrument conditions, who can achieve the following indicators atomic absorption spectrometer can be used.
--- Characteristic concentration. in the sample solution matrix consistent solution, characterized in lead concentration should not exceed 0.50μg/mL;
--- Precision. the highest concentration of the standard solution with 10 times the absorbance measured, and the standard deviation should not exceed the average absorbance
1.50%; absorbance measured 10 times the minimum concentration of the standard solution (not a "zero" standard solution), and the standard deviation should not exceed
0.50% the highest concentration of the standard average absorbance;
--- Linear curve. The curve is divided into five sections according to concentration, absorbance difference between the absorbance difference between the highest and the lowest segment of the segment
Ratio of not less than 0.90.
5 Sample
5.1 Samples should sift through the 0.100mm hole.
5.2 Samples previously 105 ℃ ± 5 ℃ baking 1h, cooled to room temperature and placed in the dryer.
