Anodic oxidation of synthetic refinery effluent on lead anode: mass transport and charge rate balance

A synthetic wastewater based on Algiers refinery real effluent was prepared and treated using anodic oxidation. Full factorial plan design was used to conduct the statistical analysis of the results. The aim of the study was to assess the interaction between current density (CD) and stirring degree...
