چکیده انگلیسی
Adsorption and electrosorption of thiocyanate (SCNâ) anions on active carbon felt electrodes were measured by UV spectroscopy and cyclic voltammetry to provide more knowledge of the application of electrosorption on high-area carbon material in industrial waste water purification. Positive polarization caused increased adsorption of SCNâ. SCNâ showed the highest electrosorption capacity at about pH 3. Reversible electrosorption of SCNâ to different extents was observed by changing the direction of polarization currents, which is possibly accompanied by the accessible surface area of C-felt being increased by positive polarization and electrochemical oxidation of SCNâ. The enhanced capacity for adsorption by positive polarization will improve reuse of active carbon felt.
