The adsorption of Cr(VI) on biochars can be suppressed by coexisting anions, but the roles of O-containing functional groups and in particular N-containing functional groups are unclear. In this study, we combined spectroscopic and mol. simulation approaches to investigate the selective adsorption of Cr(VI) on the O-rich (PB, UB1) and N-rich (UB3, UB5) biochars under strong competition of anions. The elemental anal. and pyrolysis-gas chromatog./mass spectrometry indicated that the structures of PB and UB1 were similar, and so were the UB3 and UB5. Quantification of functional groups showed that for UB1, 75.3% of Cr(VI) removal was attributed to O-containing groups, while 53.3-72.7% of that was mediated by N-containing groups in UB3 and UB5. X-ray photoelectron spectra and d. functional theory calculations confirmed that for O-rich biochars, surface complexation and strong H-bonds between carboxyl/hydroxyl and HCrO-4 improved Cr(VI) removal in the presence of anions, while for N-rich biochars, Cr(VI) adsorption was depressed by coexisting anions in the order of Cl->NO-3 >SO2-4 because of the weaker H-bond between protonated amino groups and HCrO-4. This study presents a novel approach for quant., mol.-level evaluation of the roles of biochar functional groups in the Cr(VI) removal from complex environmental systems. To complete the study, the researchers used 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .
