Abstract
Feasibility, optimisation and modelization of textile cationic dyes (TCD) removal and recovery from industrial wastewaters by batch mode capacitive deionization (BMCDI), with activated carbon (AC) electrodes, were investigated.The synergy hypothesis, AC adsorption-electrochemical double layer effects, was verified and measured by the high CDI efficiency (≈99%) which was three times higher than conventional AC adsorption, demonstrating the intensification of the TCD removal by CDI. Unlike the adsorption and biological established treatments, the BMCDI presents real environmental performance and sustainability (recycling of pristine treated water, recovery of TCD and clean regeneration of AC electrodes).This research study was mainly focused on the concentration–time (C–t) and q(X/M)–t curves of batch runs, at different pHs, applied voltages (V) or flow rates (Q). The BMCDI efficiency was measured by the final equilibrium concentration Cfineq and electrode specific adsorption, q(X/M).CDI has rarely been studied as removal and recovery method of TCD. This BMCDI approach is thus quite novel and potentially applicable.
