Methods for chemical analysis of rhodium triphenylphosphine rhodium chloride Part 1. determination of the amount of rhodium Inductively coupled plasma atomic emission spectrometry Warning - the use of perchloric acid treatment of organic matter in the amount and treatment conditions should be strictly in accordance with standards, good personal protection, should avoid Free explosion.

1 Scope

This part of GB/T 33913 specifies the method for the determination of the amount of rhodium in triphenylphosphine rhodium chloride. This part is applicable to the determination of the amount of rhodium in triphenylphosphine rhodium chloride. Measuring range. 0.5% ~ 12%.

2 principle of the method

The sample is nitric acid, perchloric acid heating on the hot plate smoke decomposition decomposition of organic matter, and then use the mixed acid rhodium can be converted into rhodium Liquid, indium as the internal standard, inductively coupled plasma emission spectrometer to determine the calculated rhodium mass fraction.

3 reagents and materials

Unless otherwise stated, only the reagents identified as analytical reagents and distilled or deionized water or comparable purity were used in the analysis. 3.1 Hydrochloric acid (ρ = 1.19 g/mL). 3.2 nitric acid (ρ = 1.42 g/mL). 3.3 Perchloric acid (ρ = 1.76 g/mL). 3.4 Hydrogen peroxide (30%). 3.5 mixed acid. three units of hydrochloric acid (3.1) with a unit volume of nitric acid (3.2) mixed with the current distribution. 3.6 nitric acid (1 1). 3.7 Hydrochloric acid (19). 3.8 indium internal standard solution. Weigh 0.1000g metal indium (mass fraction ≥ 99.9%) set.200mL beaker, add 10mL nitric acid (3.6), dissolve completely at low temperature, cool to room temperature, water into the 100 mL volumetric flask and dilute to the mark. Mix well. This solution 1mL Containing 1.000 mg of indium. 3.9 rhodium standard storage solution. Weigh 0.1000g rhodium powder (mass fraction ≥ 99.99%), placed in 50mL special hard glass tube, adding 8 mL of hydrochloric acid (3.1), 2 mL of hydrogen peroxide (3.4), the glass tube was sealed on a gasoline torch flame and the glass tube was placed in a 300 ° C furnace Complete solution. Cooling, open tube. The tube test solution with hydrochloric acid (3.7) into the 100mL volumetric flask and diluted to the mark, mix. This solution 1 mL containing 1.000 mg of rhodium. 3.10 rhodium standard solution. take six 100mL volumetric flask, respectively, the corresponding amount of rhodium standard storage solution (3.9), each add 1.00mL Indium internal standard solution (3.8), 10mL hydrochloric acid (3.1), diluted with water volume. Mix well. The rhodium content was 5.00 μg/mL, 10.00 μg/mL, 25.00 μg/mL, 50.00 μg/mL and 60.00 μg/mL. 3.11 argon (volume fraction ≥99.99%). ......
