Solubility of platinum in aqueous solutions at 25°C and pHs 4 to 10
... Solubilities ranging from 0.014 to 0.362 mg/L for platinum and up to 6 mg/L for palladium were measured. These experiments clearly demonstrate the effect of OH− ions on the solubility of PGMs with concentrations increasing with pH (i.e., with [OH−]). The data of Wood (1991) are important because it ...
