YS/T 252.1-2007: Methods for chemical analysis of nickel matte. Determination of nickel content. Dimethylglyoxime gravimetric method
This Part specifies the method for determination of nickel content in high nickel matte. This Part is applicable to the determination of nickel content in high-nickel matte. Measuring range: 20% ~ 80%. 2 Method summary The sample is decomposed with hydrochloric acid or nitric acid-potassium chlorate saturated solution. In the ammonia medium, nickel and diacetyl oxime form a red nickel diacetyl oxime precipitate, which is separated from other impurity elements. The precipitate is filtered, washed, and dried to constant weight; the amount of nickel is calculated. The amount of nickel in the mixed filtrate is extracted with chloroform under pH6.5, separated from other impurities, measured using diacetyl oxime spectrophotometry and then corrected. 3 Reagents 3.1 Hydrochloric acid (¦Ñ1.19 g/mL). 3.2 Hydrochloric acid (1 + 1). 3.3 Hydrochloric acid (1 + 24). 3.4 Nitric acid (¦Ñ1.42 g/mL). 3.5 Nitric acid (1 + 1). 3.6 Sulfuric acid (¦Ñ1.83 g/mL). 3.7 Ammonia (1 + 1). 3.8 Chloroform. 3.9 Nitric acid-potassium chlorate saturated solution: Dissolve potassium chlorate in YS/T 252.1-2007 ?
