The kinetics on open-circuit reduction of Cr(VI) by polypyrrole-modified film
Source abstract
Abstract
Polypyrrole(ppy) films were electropolymerized from a para-toluenesulfonic sodium solution on stainless steel(SS).The reduction of Cr(Ⅵ) by ppy-modified electrode at open-circuit mode was studied.The ability of oxidative ppy and reductive ppy on Cr(Ⅵ) removal was compared.It is found that the oxidative ppy could remove Cr(Ⅵ) effectively by adsorption process.However,reductive ppy displays higher removal efficiency than oxidative ppy.The kinetics of open-circuit reduction on Cr(Ⅵ) by ppy-modified film was proposed.
