1 Scope

GB/T 34609 provisions of this part of the determination of rhodium rhodium compounds. This section applies to rhodium nitrate (Rh (NO3) 3), rhodium sulfate (Rh2 (SO4) 3), rhodium trichloride (RhCl3), rhodium iodide (RhI3), rhodium acetate Rhodium octylate ([Rh (CH3 (CH2) 6CO2) 2] 2), rhodium acetylacetonate (C15H21O6Rh) Determination of rhodium content in triphenylphosphine rhodium chloride ([(C6H5) 3P] 3RhCl). Measurement range .5% ~ 50%.

2 method principle

The sample was pretreated with nitric acid, hydrochloric acid and perchloric acid, then digested in polytetrafluoroethylene tank and hydrochloric acid-hydrogen peroxide was digested under high temperature and high pressure, Chlorine complex slightly acidic solution, with rhodium nitrate hexamine cobalt complex precipitation, gravimetric determination of rhodium.

3 reagent

Unless otherwise specified, only reagents that are identified as analytically pure and secondary water are used in the analysis. 3.1 sodium nitrite. 3.2 Nitric acid (p = 1.42 g/mL). 3.3 Hydrochloric acid (p = 1.19 g/mL). 3.4 Absolute ethanol (ρ = 0.79g/mL). 3.5 ether (p = 1.19 g/mL). 3.6 perchloric acid (70.0% ~ 72.0%). 3.7 Hydrogen peroxide (30%, volume fraction). 3.8 Ammonium hexamine cobalt saturation solution Weigh 17g crystalline hexamine cobalt, add 300mL of water, heated to dissolve, with fast qualitative filter paper After filtration, dilute to 1000 mL. 3.9 Ammonium hexamine cobalt lotion Take 15mL hexamine cobalt saturated solution, diluted with water to 500mL. Note Preparation of hexamine cobalt nitrate in Appendix A.
