✦ Synopsis


A molybdophosphate anion modified electrode has been prepared in 2 M sulfuric acid solution containing PMo, ,O& by electrochemical cycling scan or simple adsorption on a glassy carbon electrode anodized before modification.

The film electrode obtained is very stable upon potential cycling in acid solution. The catalytic effect of the film for reduction of bromate was investigated in detail.

A sol-gel technique was used for the preparation of a three dimensional carbon composite electrode modified with [Cu(bpy) 2 ]Br 2 complex. A reversible redox couple of Cu(II)/Cu(I) is observed at the electrode surface. The electrochemical behavior and stability of the modified electrode was characte
