Popis: | The currentless deposition of Cu2+, Ag+, and other cations from solutions of their salts takes place on the surface of hydrogen-saturated palladium (Pd-H). It is hypothesized that this process occurs via a catalytic chemical mechanism. It is demonstrated that 80–90% of the copper deposits onto Pd-H from a CuSO4 solution in the first hour of their contact. The Pd-H system with a thin palladium coating can finely purify solutions from Cu2+ when the amount of hydrogen in Pd exceeds the amount of Cu2+ in the solution. |
