In december I studied the complex formation and its stability in Zn(II)-Sn(II)-Mo(VI)-citrate systems by cyclic voltammetry method, in a series of electrolytes with different concentrations of sodium citrate, sodium molybdate, zinc sulfate(IV), and tin sulfate (IV). All electrochemical measurements were carried out in a 95 cm3 cell, in a system with a rotating disc electrode to ensure a constant and controlled hydrodynamic conditions. The measurements were performed potentiodynamically in a three-electrode cell by means of potentiostat PARSTAT 2273.
Unfortunately I had to stop suddenly, the research because of the failure of potentiostat.
