Abstract

Abstract Zinc hydroxide nanoparticles have been used for electrocatalytic oxidation and determination of 21 parabens in aqueous solution. Zinc hydroxide nanostructures were characterized by X-ray, SEM and AFM. The kinetic parameters of 21 parabens and their chlorinated derivatives were investigated by means of cyclic voltammetry and differential pulse voltammetry as well as steady state polarization. In addition, the results of the present study indicated that the differential pulse voltammetry test was more sensitive than the cyclic voltammetry test for the determination of the kinetic data of parabens.
