Foreword

Instead of the standard YS/T 563-2006 "Determination of platinum, palladium, rhodium alloys - Determination of the amount of palladium and rhodium." Compared with this standard YS/T 563-2006, the main changes are as follows. --- Standard name by the YS/T 563-2006 "Determination of platinum, palladium, rhodium alloys - Determination of the amount of palladium and rhodium content" to "precious metals together Methods for chemical analysis of gold alloys of platinum, palladium, rhodium palladium, rhodium determining the amount of dimethylglyoxime gravimetric method, stannous spectrophotometry "; --- Measurement range from the original Pd4%, Rh3.5% revised to. Pd3% ~ 8%; Rh3% ~ 5%. This standard by the National Standardization Technical Committee of non-ferrous metals and centralized. This standard was drafted. Your research Platinum Limited. The main drafters of this standard. Luo Yijiang, race Xiang Tao, Ma Yuan. This standard replaces the standards previously issued as follows. --- GB/T 1488-1979; --- YS/T 563-2006. Precious metal alloys - Determination of the amount of the alloy of palladium, rhodium, platinum, palladium, rhodium amount Dimethylglyoxime gravimetric method, stannous chloride spectrophotometry

3 PRINCIPLE OF THE METHOD

Samples with hydrochloric acid - nitric acid mixture dissolved. In sodium bromate, sodium bicarbonate (pH8) media manipulation, palladium, rhodium and platinum was precipitated hydrated oxide points from. In dilute hydrochloric acid medium with dimethylglyoxime precipitate palladium, palladium content was measured by weight method. With stannous chloride Determination of the amount of rhodium.

4 Reagents

Unless otherwise indicated, the reagents used in this standard and vessels shall comply with the provisions of YS/T 371's. 4.1 hydrochloride (ρ1.19g/L). 4.2 hydrochloric acid (1 + 99). Nitrate 4.3 (ρ1.42g/L). 4.4 Hydrogen peroxide (30%). 4.5 Sodium bromate solution (100g/L). 4.6 sodium bicarbonate solution (50g/L). 4.7 sodium chloride solution (100g/L). 4.8 sodium chloride solution (1 + 9). 4.9 dimethylglyoxime in ethanol (10g/L), filtered to use. 4.10 stannous chloride solution (250g/L). Weigh 25g of stannous chloride dissolved in 17mL hydrochloric acid (4.1), diluted with water to 100mL, Stored in a brown bottle. 4.11 rhodium standard solution. Weigh 0.10g rhodium metal, accurate to 0.0001g (rhodium content should be not less than 99.99%), according to Predetermined YS/T 371 is dissolved. After opening the tube, the solution was transferred to 100mL volumetric flask, add 10mL of hydrochloric acid (4.1), diluted with water to the mark degree. Mix well. Each mL of this standard solution containing rhodium 1.000mg.

5 Instruments

UV-visible spectrophotometer.

6 Sample

Erase the oil sample with acetone, and then processed into chips, washed, dried, and mix.
