Abstract
AbstractDeturbidization of crude oil-polluted water by electrocoagulation was investigated using an aluminium (Al) electrode. The crude oil used in this experiment was obtained from the shell petroleum development company (SPDC) flow station at Kokori in Ethiope East local government area of Delta state. The experiment was performed in a batch electrochemical cell with an aluminium electrode in a monopolar connection. To estimate the efciency of the electrocoagulation technique, preliminary tests were conducted. And the best result was achieved at pH 8, the current dosage of 2.5A, a temperature of 298 K, and contact time of 30 min. With a turbidity removal efficiency of 84.7%. The data obtained were analysed using the pseudo-first-order, pseudo-second-order, Elovich, intra-particle diffusion, and the Boyd kinetic models. Using the regression coefficient (r2), the kinetic rates conformed to the pseudo-second-order kinetic model. The result were further analysed using different adsorption isotherms such as: Freundlich, Temkin, Langmuir, and Dubinin-Radushkevich (D-R) model. And the sorption process was found to fit best with the Langmuir adsorption isotherm with monolayer coverage of adsorbed molecules. The thermodynamics study shows that the adsorption process was endothermic and spontaneous.
