Voltamperometry of selective dissolution of binary homogeneous metallic alloy in solid/liquid-phase mass-transfer conditions

Una técnica voltamperométrica ayudó a resolver el problema existente en la disolución aniónica selectiva cinéticamente reversible de una aleación homogénea entre dos metales a relaciones comparables de masas transferidas de iones metálicos disueltos y átomos en fase sólida.

The problem of anodic kinetically reversible selective dissoln. of homogeneous metal A-B alloy at comparable rates of mass transfer of dissolved metal ions (in the liq. phase) and atoms A (in the solid phase) was solved.  The conditions of purely solid-phase diffusion mass transfer limitations during the selective ionization of an alloy system were established.  With the use of numerical simulation of the voltammetric process the role of potential sweep rate, content of an electroneg. component in an alloy, concn. of ions in soln. and diffusivity in contacting phases in the mixed kinetics of the process is established.
