The Separation of Platinum Group Metals (PGM) in Chloride ...

Abstract Styrene-divinylbenzene copolymers incorporating isothiourea functional groups show a remarkable affinity for platinum-group-metal (PGM) ions in chloride media, The mode of ion binding to the resin depends on the equilibria between isothiourea (free base) form and isothiouronium (conjugated acid) form, This in return is related to matrix structure, A. resin, Monivex, which shows high ...

Separating the Platinum Group Metals by Liquid–Liquid ...

To extract the platinum group metals from the ore, and to refine them to the very high purity required for their many applications, requires a multitude of complex operations. At present the final refining stage that produces the individual platinum group metals is carried out by selective precipitation from a solution of mixed platinum group metals, but this is inefficient as far as the ...

Liquid–liquid extraction - Wikipedia

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Fuel cells operate by the transport of a mobile ion through an electrolyte separating two chambers with electrodes, as shown in the diagram above. Because the electrons cannot pass through electrolyte they have to pass through the external circuit, generating electrical power from the oxidation of the fuel. The main advantages of fuel cells are that they have no moving parts, and are thus ...
