“…The adsorption band at 1120 cm −1 corresponded to the stretching vibration of the C-O bond. The signal at 592 cm −1 was the Fe-O adsorption peak, which indicated that the nZVI was oxidized on the BC [36]. These functional groups were believed to play a crucial role in the adsorption of ONZ and the support of nZVI.…”

“…These functional groups were believed to play a crucial role in the adsorption of ONZ and the support of nZVI. These functional groups immobilized nZVI and reduced the electrostatic attraction with nZVI [36]. A previous study indicated that nitroimidazoles can be adsorbed onto organic matter through interactions between the π electrons in the aromatic rings [37].…”

“…The mechanisms for higher As removal capacities by modified biochar included more adsorption sites for arsenic(V) removal, ligand exchange between As(V) anion, the hydroxylated surface, and H bond (Wang et al 2016(Wang et al , 2017dYoon et al 2017;Zhang et al 2016a;Zhou et al 2017c). Similarly, the most popular modification methods were Fe/Mn oxides and nanoscale zero-valent iron-supported biochars for Cr(VI) removal (Dong et al 2017;Duan et al 2017;Qian et al 2017;Su et al 2016;Wang et al 2017a). Greater electrostatic attraction and reduction capacity might be attributed to the higher removal of Cr(VI) by modified biochar (Han et al 2016b;Qian et al 2017;Su et al 2016).…”

“…3 As one of most toxic heavy metal elements in water, Cr(VI) could stay in the organism for a long period, resulting in a high risk of cancers, due to carcinogenicity, persistence, and bioaccumulation. 4,5 In general, Cr-containing sewage is oen derived from industry discharge, e.g. electroplating industry, textile industry, curriery, and metallurgy.…”
