摘要：
In the present work RHDAC electrode was used to electrosorption of hexavalent chromium and fluoride (HCAF) by capacitive deionization from the aqueous feed. In this study multicomponent isotherm (MCI) modeling were done with different six MCI models for simultaneous removal of HCAF using RHDAC electrodes. This RHDAC electrode performance was indicated the simultaneous maximum electrosorption 2.47 and 2.34 mg/g for HCAF respectively for 100 mg/L aqueous feed. The results show that MCIM3 (Extended Langmuir) and MCIM5 (Non modified Redlich Peterson) models were found more fit to with experimental data with lower MPSD for both HCAF than other MCI models. The RHDAC was an effective electrode material for HCAF sorption from low concentrated feed.
