Selective transfer of gold (III) in chloride solutions through polyurethane films

Abstract
Gold (III) chloride can be extracted by solvating solvents and this extends to polyurethane foams. This study has confirmed that gold (III) chloride can be rapidly transported through polyurethane films. The rate of transfer follows first-order kinetics with the rate-determining step being transport through the film. This has been confirmed by measuring the rate of stripping of gold (III) pre-loaded into the film and by using films of different thicknesses. Diffusion coefficients for the transport of gold (III) are compared with those from studies using liquid supported membranes.
The loading isotherm of gold (III) in the polyurethane film has been obtained. Iron (III) and platinum (IV) are transported at negligible rates while tri-iodide ions are strongly absorbed by the film at a lower rate.
