3 Method summary

The sample is dissolved in perchloric acid-hydrofluoric acid-nitric acid, and cobalt is separated as a precipitate of cobalt nitronate in an acetic acid medium to which tartaric acid is added. The cobalt content was determined by EDTA standard solution titration.

4 reagents and materials

Unless otherwise stated, only analytically pure reagents and distilled or deionized water or water of comparable purity were used in the analysis. 4.1 Ammonia. 4.2 Perchloric acid. 4.3 Concentrated nitric acid. 4.4 Hydrofluoric acid. 4.5 Glacial acetic acid. 4.6 Hydrochloric acid (1+1). 4.7 potassium nitrite solution A (precipitate). Weigh 50g of potassium nitrite dissolved in appropriate amount of water, add 8mL of glacial acetic acid, dilute with water to 100mL, shake well. 4.8 Potassium nitrite solution B solution (washing solution). Measure 40 mL of potassium nitrite solution A, 8 mL of glacial acetic acid, and dilute to 500 mL with water. Shake well. 4.9 Potassium carbonate solution (20%). 20 g of potassium carbonate was dissolved in 100 mL of water. 4.10 Tartaric acid solution. 100 g of tartaric acid is dissolved in 100 mL of water. 4.11 Ammonia-ammonium chloride buffer solution (pH≈10).
