Summary: In this study, sustainable nanocomposites were successfully prepared from agriculture waste (rice husk)-derived biochar precursor, and loaded with nickel-doped, base-treated titanium dioxide nanomaterials for efficient lead (Pb2+) removal from aqueous media. The optimized sample (Ni0.01@Na-TiO2/BC) exhibited a high Pb2+ adsorption capability of 122.3 mg g(-1) under the optimum adsorption conditions, attributed to its specific surface area and excess functional sites. The kinetic and isothermal examinations showed that the adsorption of Pb2+ followed pseudo 2nd order and Langmuir models. Furthermore, the optimized sample demonstrated superior adsorption selectivity for Pb2+ ions in a multi-metallic system compared to other ions.

Summary: This study evaluates the performance of magnetic CoFe2O4/Al2O3 nanocomposite in removing Cd(II) and Pb(II) metal ions from wastewater. The nanocomposite is compared with bare CoFe2O4 nanoparticles. The nanocomposite shows smaller particle size, increased surface area and porosity, higher magnetization, and uniform distribution with a spherical structure compared to the nanoparticles. The optimization experiments demonstrate that the nanocomposite has significantly enhanced removal efficiency for Cd(II) and Pb(II) ions and higher adsorption capacity compared to CoFe2O4. The effect of temperature on removal efficiency is also studied.

Summary: In this study, Zeolitic imidazolate framework-8 (ZIF-8) was evenly loaded on the surface of KI-doped TiO2, resulting in a ZIF-8@TiO2 (KI) adsorption photocatalyst with excellent adsorption and photocatalytic properties. The doped I inhibited grain growth, reduced TiO2 crystallite size, narrowed the band gap width and improved light utilization. The combination of ZIF-8 and TiO2 increased the specific surface area and reaction sites. The photocatalytic performance of ZIF-8@TiO2 (KI) was validated using Congo red, showing high degradation efficiency.
