Abstract |
|
|
| Capacitive deionization (CDI) is a second-generation desalination process used to desalinate brackish water. It is an inexpensive and environmentally friendly method. A study was performed to examine the suitability of using acidified activated charcoal in CDI technology for the production of clean water. CDI electrochemical measurements of acidified activated charcoal revealed a high specific capacitance of 191.7 Fg-1 at 1 M compared to 160 Fg-1 at 0.1 M indicating an active potential for ion electrosorption at higher concentrations. The results of symmetries CDI cells prove that it is possible to significantly enhance the electrosorption performance of acidified activated charcoal during electrochemical desorption at 1.8 V (4.1 mg/g) using 100 μs cm-1.
