摘要:To improve the adsorption properties of activated carbon (AC), powder-hydrolyzed feathers (PHF) bio-modifier and Trapa natans husks (TH) were used for AC preparation to enhance its physicochemical and adsorption properties. The physicochemical properties of the original activated carbon (AC) and PHF-modified activated carbon (ACF) were systematically examined by N-2 adsorption/desorption, elemental analysis, Boehm titration, and X-ray photoelectron spectroscopy (XPS) techniques. The ACF exhibited higher S-mic/S-BET (35.97%) and V-mic/V-tot (45.61%) than that of AC (16.68% and 6.56%), although only slightly decreases in the S-BET and V-tot observed for the ACF after PHF modification. Meanwhile, ACF shows more functional groups (O/N-containing functional groups) due to in situ modification. Furthermore, the batch adsorption experiments revealed that ACF showed much higher adsorption capacity for Cd(II) and Ni(II) (50.25 and 46.73 mg/L) than that of AC (33.90 and 31.15 mg/L). According to the results of fitting of adsorption models and the XPS analysis, microporous entrapment surface complexation, cation exchange and electrostatic attraction play key roles in Cd(II) and Ni(II) removal.
