Summary:The solution chemistry of palladium has been examined directly in seawater by ultraviolet absorbance spectroscopy. Results indicate that chloride complexation strongly suppresses the hydrolysis of Pd super(2+) in seawater. At 25 degree C and salinity equal to 36, hydroxy complexes account for similar to 18% of the total palladium and the remainder is present principally as PdCl sub(4) super(2) super(-). The enormous reactivity of Pd super(2+) relative to Ni super(2+) appears to be moderated, in seawater, by extensive complexation of Pd super(2+) with chloride ions.
