Adsorption and electrochemical reduction of Co(II)-dimethylglyoxime on mercury

Cobalt and nickel in aqueous solutions can be determined by adsorptive striping voltammetry, using dimethylglyoxime as a complexing agent in order to accumulate the metals efficiently on a mercury surface. In borate buffer solution (pH 9.3) capacity results suggest that Co(II)-dimethylglyoxime (Co(H...
