Current study reports the adsorption of acephate (organo-phosphorus pesticide) onto modified adsorbent and its electrochemical regeneration under various electrochemical conditions including current density, charge passed, and treatment time. The adsorption kinetics was also evaluated using Freundlich, Langmuir, Dubinin�Radushkevich, and Tempkin isotherm models. The kinetic data were fitted to pseudo first and second order kinetic models and adsorption equilibrium was achieved in 60 min with an adsorption capacity of 4 mg g�1. Langmuir isotherm model was found in best fit with experimental data. Five adsorption/regeneration cycles showed no loss to material and adsorption capacity with 100 regeneration efficiency. © 2020 Taylor & Francis Group, LLC.
