Determination of zinc content; - Part 4. Determination of cadmium; - Part 5. Determination of nickel content; - Part 6. Determination of cobalt content; - Part 7. Determination of arsenic; - Part 8. Determination of bismuth; - Part 9. Determination of molybdenum content; - Part 10. Determination of tungsten; - Part 11. Determination of silver; - Part 12. Determination of sulfur content; - Part 13. Determination of gallium content, indium content and thallium content; - Part 14. Determination of germanium content; - Part 15. Determination of selenium content; - Part 16. Determination of tellurium; - Part 17. Determination of thallium content; Part 18. Determination of copper content, lead content, zinc content, cobalt content and nickel content. This part is Part 6 of GB/T 14353. This part of the GB/T 14353.6-1993 "copper ore, lead ore and zinc ore chemical analysis of cobalt determination." This part compared with GB/T 14353.6-1993, the main changes are as follows. --- increase the warning, warning content; --- modified the sample drying temperature; --- removed the first dibromide - sulfosalicylic acid - ammonium hydroxide - ammonium chloride bottom polarography, the second 5 - Cl - PADAB light Degree method.

3 principle

Samples by hydrofluoric acid, aqua regia, perchloric acid (or sodium peroxide, sodium hydroxide) decomposition, hydrochloric acid, boric acid solution dissolved salt (or with oxygen Sodium hydroxide, sodium hydroxide, molten iron, water, extraction, filtration, precipitation with hydrochloric acid), in 5% hydrochloric acid medium, the use of air - acetylene flame, at the wavelength 240.7nm, with an atomic absorption spectrophotometer to measure the absorbance, calculate the amount of cobalt.

4 reagent

This part uses analytical pure reagents and analytical laboratory water complying with GB/T 6682, unless otherwise stated. 4.1 Sodium peroxide. 4.2 Sodium hydroxide. 4.3 hydrofluoric acid (ρ1.13g/mL), warn. hydrofluoric acid is toxic, with strong corrosive, should wear gloves during operation to prevent contact with the skin 4.4 perchloric acid (ρ1.67g/mL), warning. the reagent for the explosive items, careful operation 4.5 anhydrous ethanol. 4.6 fresh water (HCl HNO3 = 3 1) fresh preparation. 4.7 Hydrochloric acid (1 1). 4.8 boric acid solution (60 g/L). 4.9 Sodium hydroxide solution (20 g/L). 4.10 cobalt standard solution preparation. a) cobalt standard stock solution [ρ (Co) = 100.0 μg/mL]. 0.1000 g of metal cobalt [w (Co) = 99.99%] was weighed and placed in 100 mL Beaker, cover the surface of the dish, along the cup wall by adding 20mL nitric acid (1 1), heating dissolved, low temperature evaporated, with a small amount of water to rinse the surface Dish, add 5mL hydrochloric acid (ρ1.19g/mL), dry at low temperature, repeat once. 10 mL of hydrochloric acid (ρ1.19 g/mL) was added to dissolve the cobalt Salt, cool, water into the 1000mL volumetric flask, and diluted to the mark, shake, spare.
