Abstract:In this work, the removal of hardness was studied from tap water taken from Aljadriya municipal water network-Baghdad. A parallel plate electrochemical cell was constructed using two graphite electrodes as anode, and three aluminum electrodes as cathodes. The electrodes were connected to a power supply that provides direct electrical current to the cell. Results showed that a removal efficiency of 85% can be obtained at pH of 7.5and electrical voltage of 28.5 volt with retention time of 60 minutes. The high ef… 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.
