Summary: In this study, a graphene oxide-bismuth tungstate (GO-Bi2WO6) nanocomposite was synthesized and used as an efficient adsorbent for the removal of Pb2+. The results showed that the optimal conditions for adsorption were pH = 5.0, 20 mg adsorbent, and 20 min contact time, with a removal efficiency above 94% for 50 mg L-1 Pb2+. The adsorption of Pb2+ followed the Freundlich isotherm with a maximum adsorption capacity of 128 mg g(-1). The pseudo-second-order kinetic model was found to best describe the adsorption process. Thermodynamic analysis revealed that the adsorption of Pb2+ onto the GO-Bi2WO6 nanocomposite was an endothermic and spontaneous process, with better performance at higher temperatures.

Summary: In this research, a novel green tillite-based adsorbent (CMT) was synthesized by modifying the surface of natural/pristine tillite (PT) with Chrysophyllum albidum stem bark extract. CMT showed higher efficiency and adsorption capacity for Cr(VI) removal compared to most materials used for this purpose. The results also demonstrated the reusability of CMT and the chemisorption as the rate-controlling step. This study highlights the potential of Chrysophyllum albidum stem bark extract anchored on tillite as a green adsorbent for efficient Cr(VI) removal from polluted water.

Summary: Biological desulfurization processes of landfill gas produce a large amount of biologically produced S (BPS) as a byproduct, which has been shown to effectively remove Cd2+ from aqueous solutions with a higher adsorption capacity compared to granular activated carbon (GAC). The kinetics of Cd2+ removal by BPS is a two-stage process, with favorable and endothermic thermodynamic parameters. Results indicate that BPS can be recycled as a novel adsorbent for Cd2+ removal from wastewater.

Summary: In recent years, research teams have shown increasing interest in using MIL-101(Cr) in various applications. A major challenge in the synthesis of MIL-101(Cr) is the removal of unreacted terephthalic acid (ur-H2BDC) during post-synthesis purification. This study focuses on the development of a method using aqueous solutions of sodium bicarbonate (NaHCO3) to remove ur-H2BDC, with a 0.06 M NaHCO3 solution for 24 hours proving to be the most efficient.

Summary: In this study, a solid-phase microextraction coating based on MOF-199 was synthesized on a stainless steel substrate using an in situ solvothermal method. The factors affecting the physicochemical characteristics of the MOF-199 coating, such as solvent, metal salt, chemical modulator, and batch composition, were investigated. The thickness of the MOF-199 coating increased with the addition of acetic acid and decreased significantly when using butanol as the solvent compared to ethanol. Different metal precursors resulted in varying thicknesses of the MOF-199 coating.

Summary: This study investigated the recovery of K+, NH4+-N, and PO43--P from hydrolyzed urine by technical integration. Na-chabazite was selected as the adsorbent due to its high K recovery efficiency and additional P recovery capacity. The study found that the competition between NH4+ and K+ was diminished when their molarity is the same, leading to improved K adsorption onto Na-chabazite.

Summary: Selective removal of one ligand in mixed-ligand MOFs creates hierarchical pore architectures with improved adsorption capacity for glyphosate removal from water. The Ti-OH groups resulting from ligand removal serve as effective anchor points for glyphosate uptake. The introduction of additional mesopores has significantly increased the adsorption capacities, making these MOFs among the best-reported adsorbents.

Summary: This research studied the stability and reactivity of green iron oxide nanoparticles (EL-Fe NPs) synthesized from Eucalyptus globulus leaf extract in removing NO3- ions from polluted water. Various characterization techniques were used to analyze the EL-Fe NPs, and the effect of different factors such as contact time, pH, KCl salt, and anions on the adsorption of NO3- by EL-Fe NPs was evaluated. The results showed that EL-Fe NPs had irregular nano-particulate structures and exhibited strong adsorption capacity for NO3- at certain conditions, but the adsorption was influenced by pH, salt concentration, and the presence of phosphate ions.

Summary: Springtime road dust in northern latitudes can have significant impacts on air quality and public health. This study analyzed PM10 samples collected near a road site in Prince George, British Columbia, and identified high road dust days based on PM10-2.5 concentrations. The results showed that high road dust days had higher levels of trace elements in PM10, as well as lower humidity and precipitation and higher temperature and air pressure. The complex relationship between road dust and weather highlights the need for further research on the health effects of chemical mixtures from road dust exposure.

Summary: Wastewater reuse is an important way to overcome water resource issues, and in this study, a heterogeneous Fenton reaction was used to treat a non-biodegradable organic contaminant in synthetic seawater. The optimal conditions were determined to be using 3.1 g/L catalysts and 12.95 mM H2O2, which could completely remove 33.12 mg/L dye. Treatment in a fluidized bed reactor significantly improved the dye removal efficiency and reduced the treatment time. The synthesized catalysts maintained acceptable performance for up to 6 cycles after regeneration.

Summary: This study focuses on enhancing the CO2 adsorption capacity of activated carbon composites by incorporating metal oxides. AC/MgO and AC/Fe3O4 composites showed adsorption capacities of 38.567 mmol g(-1) and 71.963 mmol g(-1), respectively, at 298.15 K and 5 bar. The adsorbents maintained adsorption capacities of 94.1%, 97.9%, and 96.5%, respectively, after six consecutive cycles. These findings highlight the promising potential of AC/MgO composites as effective adsorbents for CO2 capture applications.
