Abstract

Electrochemical behavior of hypochlorous acid (HClO) have been studied at boron-doped diamond (BDD) electrodes in physiological pH solution. The electrochemical measurements were performed in one-compartment electrochemical cell using cyclic voltammetry technique. A solution of 0.5 M phosphate buffer solution has been selected as the supporting electrolyte. Cyclic voltammograms of NaClO standard solutions showed the best response at optimum pH of 6.6 at the potential reduction of +0.1 V. Linear calibration curve (R2=0.9953) can be achieved at a NaClO concentration range from 1.68 to 5.86 mM with an estimated limit of detection (LOD) of 0.46 mM.
