Abstract:Treatment of effluents discharged from mechanical machining of copper and copper alloys for removal of cutting oils and toxic copper ions by electrocoagulation was studied using a cell containing two steel electrodes and a built-in heat transfer facility. Current density, initial pH of the solution, temperature, starting pollutants' concentrations, amount of NaCl supportive electrolyte, and the impact of gas sparging were investigated. Response surface methodology was used to correlate % oil removal, % copper … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
