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
