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 www.ChineseStandard.net ? Buy True-PDF ? Auto-delivery. Page 6 of 10 nitric acid (3.4) until saturated. 3.10 Potassium sodium tartrate solution (200 g/L), filter it before use. 3.11 Ammonium acetate solution (200 g/L), filter it before use. 3.12 Sodium thiosulfate solution (200 g/L), filter it before use. 3.13 Dimethylglyoxime ethanol solution (10 g/L), filter it before use. 3.14 Dimethylglyoxime-sodium hydroxide solution (10 g/L): Dissolve 15 g of sodium hydroxide in 100 mL of water. After cooling to room temperature, dissolve 1 g of dimethylglyoxime in the solution. Mix well. 3.15 Ferric persulfate solution (50 g/L). 3.16 Nickel standard stock solution: Weigh 0.1000

This Standard specifies conditions for the determination of the reduced viscosity (also known as viscosity) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins may contain small amounts of unpolymerized substances (e.g. emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the course of the polymerization. This Standard is not applicable, however, to resins having a volatile-matter content in excess of 0.5%, when determined in accordance with GB/T 2914. In addition to this, it is not applicable to resins which are not entirely soluble in cyclohexanone.
