Experimental and theoretical studies on electrocatalytic oxidation of arsenic (III) and iron (II) using chlorpromazine: Electrochemical and mechanistic study by digital simulation in liquid phase

The electrochemical properties of aqueous chlorpromazine (CPZ), at pH2–8, were investigated by cyclic voltammetry at a boron doped diamond (BDD) electrode. The standard potential and kinetic parameters for CPZ were obtained by fitting experimental cyclic voltammograms to those generated by the DigSi...

Description
Summary:	The electrochemical properties of aqueous chlorpromazine (CPZ), at pH2–8, were investigated by cyclic voltammetry at a boron doped diamond (BDD) electrode. The standard potential and kinetic parameters for CPZ were obtained by fitting experimental cyclic voltammograms to those generated by the DigSim program. The electrogenerated oxidized form of CPZ has been used as an efficient organic catalyst for the oxidation of As (III) and Fe (II) at BDD electrode immersed in aqueous media. The determination of catalytic rate constant (Kcat) was again accomplished by fitting experimental cyclic voltammograms with simulated ones. [Display omitted] •The electrochemical behavior CPZ on the surface of BDD electrode was investigated.•The electrocatalytic oxidation of As (III) and Fe (II) ions were studied by CPZ.•The kinetic parameters, E0′ and Kcat were obtained by the DigSim3 program.
