| titleOfInvention | Method of coulometric determination of platinum and silver |
| abstract | The invention relates to electrochemical methods of analysis, in particular, to coulometry at a controlled potential, and can be used to analyze industrial concentrates and process solutions containing noble metals. The purpose of the invention is to ensure the simultaneous determination of platinum and silver in the presence of palladium, an increase in selectivity and expressivity. This goal is achieved by the fact that the P method of coulometric determination of noble metals consists in the electrochemical reduction of platinum (IV) to platinum (II) at a potential of 0.15 to 0.20 V relative to a saturated chlorine-silver electrode in a 2 M acid solution in the presence of a complex of a 0.1 M potassium rhodanide complex and measuring the amount of electricity spent on the process of platinum reduction, after the reduction of platinum (IV), silver (I) is reduced to silver (0) at a potential of t is 0.28 to –0.32 V, silver (0) is electrochemically oxidized to silver (I) at a potential of 0.25 to 0.3 V, and the amount of electricity consumed in the process of silver oxidation is measured. from 9 |
