Electrochemical Treatment Of Metal-Bearing Aqueous Wastes Based On Novel Forms Of Carbon, Yue Xu

Graduate Theses, Dissertations, and Problem Reports

Electrochemical remediation is an economic approach for long-term clean-up of metal-bearing aqueous wastes because it provides a means of continuous, selective removal of metal contaminants and offers terminal processes for recovery of the metals. In this study, three forms of novel carbon material were tested as electrodes for the removal of heavy metals and radionuclides from aqueous wastes by electrodeposition and/or electrosorption.;Copper and lead ions in aqueous solution were effectively removed by electrodeposition on two of the carbon electrodes. The continuous, single-pass deposition through a small laboratory-scale cell removed 99% of copper and 83-88% of lead, respectively. On the other …
