The object of this study is to prepare iron species-impregnated granular activated carbon as particleelectrodes in order to improve their adsorption and electrocatalytic degradation capacity in Benzothiazoleremoval.The incorporation of Fe-containing catalysts was performed by Fe(NOspectroscop3)y,3impregnation.The obtainedsamples were characterized by BET,Fourier transform infrared SEM-EDS,powder X-raydiffraction,X-ray photoelectron spectra and TG.Compared with pure activated carbon,this modified particleelectrodes show higher static adsorption capacities and TOC removal,which have respectively increased by25.9%and 54.4%.Both physisorption and chemisorption exist in the process of benzothiazole adsorption,wherethe latter plays a major role.In this way,the Fe-containing catalysts on modified particle electrodes aredemonstrated to make a greater contribution to the improvement of electrocatalytic degradation by decreasing theactivated energy by 32%.
