Abstract

The solution chemistry of palladium has been examined directly in seawater by ultraviolet absorbance spectroscopy. Our results indicate that chloride complexation strongly suppresses the hydrolysis of Pd2+ in seawater. At 25 °C and salinity equal to 36, hydroxy complexes account for ~18% of the total palladium and the remainder is present principally as PdCl42-. Strong similarities previously reported for Pd and Ni distributions in seawater appear to have dissimilar origins at the molecular level. The enormous reactivity of Pd2+ relative to Ni2+ appears to be moderated, in seawater, by extensive complexation of Pd2+ with chloride ions.
