Web7 Jan 2024 · Dissolved metal concentrations commonly decreased with distance from the vents, as to be expected, however, certain element/Fe ratios increased, suggesting a higher solubility of these elements and/or their stronger stabilization (e.g., for Zn compared to Fe). WebIn the case of palladium, nitrate ions in the solution oxidised the metal. A chloropalladate (II) complex between the oxidised metal and chloride anions formed and was stable at the low pH. In a matter of hours, the palladium had fully dissolved in solution, and the palladium metal was then recovered via reductive precipitation using ascorbic acid.
