Manganese oxide-modified biochar derived from discarded mushroom-stick for the removal of Sb(III) from aqueous solution

Wenjian Mao et al.

Summary: In this study, discarded mushroom-stick was used to prepare MnO2-modified biochar (MBC) with excellent adsorption capacity for Sb(III) removal. Characterisation methods revealed that MBC has a high specific surface area and mesoporous structure, with manganese oxides and hydroxyl groups playing a key role in the adsorption process. The adsorption of Sb(III) onto MBC was identified as chemisorption, involving monolayer and multilayer heterogeneous chemisorption processes. The study concludes that MBC is a promising adsorbent for removing Sb(III) from contaminated water.

Highly efficient As(III) removal through simultaneous oxidation and adsorption by N-CQDs modified MIL-53(Fe)

Haoyun Chen et al.

Summary: This study presents the use of nitrogen doped carbon quantum dots (N-CQDs) modified oil vine-like structural MIL-53(Fe) for highly efficient removal of aqueous arsenites [As(III)]. The photocatalytic oxidation of As(III) and simultaneous adsorption of the generated arsenate [As(V)] were achieved, with N-CQDs3/MIL-53(Fe) exhibiting over 6 times higher As(III) oxidation ability and removal efficiency compared to pure MIL-53(Fe). The enhanced performance of N-CQDs3/MIL-53(Fe) is attributed to accelerated separation of photogenerated electron-hole by in situ embedded N-CQDs. Experimental analysis and density functional theory (DFT) calculations confirmed that the edge structure of C/O site significantly improves As(III) removal ability through the formation of bidentate C-O-As bonds and occupying coordinatively unsaturated atoms. Therefore, N-CQDs3/MIL-53(Fe) offers a new potential strategy for the development of high efficient MOF-based materials for As(III) removal.

Summary: The coupled adsorption-photocatalytic oxidation process using boron-doped black TiO2/g-C3N4 nanocomposite as a photocatalyst enhances the removal efficiency of arsenite contaminants by converting As(III) to As(V) and simultaneous adsorption. The enhancement of arsenic adsorption is attributed to the chemical complexation and hydrogen bond, with B-OH bonds playing a dominant role. The photocatalytic oxidation mechanism of the as-synthesized B-TiO2/g-C3N4 is attributed to the synergism of superoxide radicals, hydroxyl radicals, and photogenerated holes.
