Poly(Vinyl Alcohol)-Bonded Carbon Electrodes for Desalination of Brackish Water Using Capacitive Deionization (original) (raw)

2020, Journal of The Institution of Engineers (India): Series E

Permeable carbon atoms or aerogels support novel electrode materials. It is essential to improve the wetting surface area of carbon electrode for higher Capacitive Deionization (CDI) potency. To enhance the wettability of CDI electrodes, poly(vinyl alcohol) (PVA) binder (a water-soluble polymer) was used to fabricate the carbon electrodes, followed by the cross-linking of PVA with Glutaric Acid (GA). Morphological characteristics of modified electrodes were ascertained by Scanning Electron Microscopy. The primary purpose of this work is to investigate the desalting performance of PVA-bonded carbon electrodes by arranging a modified electrode with activated carbon powder and to observe its efficiency at a varied initial concentration of salt (400-1000 ppm). This makes CDI a feasible and economical means for the desalination of brackish water. The energy consumption during experiments was low, i.e., 2-5 kWh/m 3 of desalted wastewater.
