Summary: The study found that CoFe2O4 and CoFe2O4-Chit particles are suitable for treating dye-contaminated wastewater, with CoFe2O4 having a higher adsorption capacity than CoFe2O4-Chit. In single-component solutions, the adsorption of CR/MO followed pseudo-first-order and pseudo-second-order kinetics models, while in binary solutions, the adsorption on CoFe2O4 better followed the pseudo-second-order kinetics model.

Summary: A new water stable MgO-PVP composite was prepared by hydrothermal method, showing higher surface area and adsorption capacity than plain MgO. The adsorption mechanism involved electrostatic force and ion exchange, with kinetic mainly controlled by film diffusion. Langmuir and DR isotherms were well fitted with experimental results, and dye removal capacity decreased with increasing initial pH value. The negative ΔG values indicated a spontaneous adsorption process.

Summary: In this study, hexadecyl trimethyl ammonium bromide (CTAB) was used to modify orange peel biochar (OBC) to produce CTAB-modified orange peel biochar (NOBC) in order to enhance the adsorption effect of biochar on Congo red dye. The adsorption performance and mechanism of NOBC on Congo red dye were investigated. The results showed that NOBC had a higher adsorption capacity and faster equilibrium time compared to OBC. The adsorption of CR by NOBC was influenced by the initial concentration, adsorption time, and solution pH. The adsorption data of CR on NOBC were consistent with the Langmuir isothermal adsorption model and the Pseudo-second-order model, and the mechanism mainly involved electrostatic attraction and surface adsorption.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
