The influence of different halides on electrochemical incineration of oxalic acid was studied.

However, with halides, the rate of the electrochemical incineration was increased significantly, following the order F- > Br- > Cl-, and the rate of the mediated process was practically independent of applied current density.

Abstract
The influence of different halides on electrochemical incineration of oxalic acid was studied. Experiments were initially carried out at a Pt electrode in alkaline media, in which case, in the absence of mediating effects, a slow electroxidation was observed. However, with halides, the rate of the electrochemical incineration was increased significantly, following the order F- > Br- > Cl-, and the rate of the mediated process was practically independent of applied current density. An explanation has been attempted for the role of halides, in relation with the oxygen evolution reaction, concomitant with the electrochemical incineration.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
