The modified electrode material
demonstrated enhanced electrosorption capacity and reduced physical sorption at the pores, so desorption is more
efficient. An innovative approach for desorption of the saturated activated carbon electrodes has been tried using
ultrasonic vibration and increased temperature, the results of regeneration in water, aided by ultrasonic at 20°C and
50°C are presented as well. Cyclic voltammetry experiments at various scan rates were conducted using a potentiostat
to analyse the electrical double-layer capacitance of the activated carbon materials. This preliminary study
demonstrated that activated carbon granules have the potential to be cost-effective electrode materials for desalting
brackish water. The improvement of the electrosorption efficiency can be achieved by surface modification by
chemicals and metal oxide nanoparticles such as TiO
