Summary: Through KOH activation, high surface area Douglas fir biochar obtained from commercial syn-gas production shows remarkable enhancement in heavy metal adsorption capacity for Cr(VI), Pb(II) and Cd(II). The adsorption process follows pseudo-second order kinetics and the Langmuir adsorption model for all three metals. The desorption study reveals that Pb(II) adsorption onto KOH-activated biochar surface is reversible, while portions of Cd(II) and Cr(VI) adsorbed strongly onto the biochar cannot be desorbed by typical solutions.

Summary: The study investigated the use of a cheap, high-efficiency, and eco-friendly adsorbent as an alternative to activated carbon coated Maghemite nanoparticles for removing lead and cadmium ions from aqueous solutions. The adsorbent showed good fit with Langmuir, Temkin and Freundlich isotherm models, and the maximum adsorption capacity for Pb (II) and Cd (II) ions was determined. The study also examined the kinetics and thermodynamics of adsorption, and demonstrated that Maghemite nanoparticle coated activated carbon derived from agricultural biomass is a promising option for removing metals from industrial effluents due to its cost-effectiveness, high efficiency, and environmental friendliness.

Summary: Aminated lignins exhibited optimal adsorption capacities for Cd(II) and Pb(II) metal ions under neutral conditions, with the primary amine group showing the highest adsorption capacities. The adsorption behaviors followed Langmuir isotherm and pseudo-second-order kinetics, and the thermodynamic studies revealed that the adsorption processes were spontaneous and endothermic. These results demonstrate that aminated lignins are promising adsorbents for the removal of Cd(II) and Pb(II) metal ions.

Summary: The main objectives of this study were to synthesize a new solid-supported ionic liquid (SSIL) and evaluate its performance as an extractant for removing Pb(II) ions from aqueous solutions. The SSIL, named Si-TS-SSIL, was synthesized by chemically immobilizing a thiosalicylate-based ionic liquid onto activated silica gel. The performance of Si-TS-SSIL was evaluated through removal experiments, and it exhibited a maximum removal capacity of 8.37 mg/g. The kinetics study showed that the removal process followed the pseudo-second order model, while the isotherm study indicated that the Freundlich isotherm model provided a better fit.

Summary: Due to the decrease in environmental pollution and energy crisis, it is necessary to find an excellent solution to utilize visible light with photocatalyst technology. Constructing heterostructure photocatalysts with metal-organic frameworks (MOFs) and graphitic carbon nitride (g-C3N4-Co) is a powerful approach to achieve high performance in visible-light photocatalysis. In this study, a heterostructure photocatalyst TMU-22/g-C3N4-Co, composed of Zn-based MOF and cobalt-doped graphitic carbon nitride, was prepared and showed superior photocatalytic activity in the aerobic oxidation of benzyl alcohol under visible-light irradiation. The enhanced separation of photogenerated electron-hole pairs and increased visible-light absorption were the main factors contributing to its high performance.

Summary: The effect of nanosilica modification on the mechanical properties of unsaturated polyester composites reinforced with pure jute and hybrid jute-high tenacity polyester (HTPET) fabrics was investigated. The study found that nanosilica modification improved adhesion between the polyester fibers and the matrix, causing surface roughening. However, the adhesion of jute fibers reduced due to the filling and smoothing of their inherent roughness. The hybrid sample with polyester fibers in its outer layers showed the largest increase in flexural and impact properties.
