Summary: This study aimed to synthesize zeolite-based hydrogel composites for decolorization of real textile wastewater. The hydrogel was created via initial bridging with polyvinyl alcohol and sodium alginate, with zeolite particles distributed throughout the matrix. Response Surface Methodology was used to determine optimal adsorption conditions. The hydrogel composite achieved 86% color removal and a 166 Pt-Co/g adsorption capacity. The composite followed a pseudo-second-order kinetics model and a Langmuir adsorption isotherm. The study also demonstrated the potential of these particles as low-cost adsorbents for color removal from industrial wastewater.

Summary: The study focused on the transformation of natural zeolite to Na-zeolite P (NaP zeolite) using a top-down hydrothermal approach. It was found that NaP zeolite has a higher specific surface area and more micropores compared to natural zeolite, leading to increased removal capacity for Sr and Ni. Additionally, the NaP zeolite showed enhanced cation exchange capacity, making it more practical for removing mixed radionuclides from waste solutions.

Summary: Pure SSZ-13 zeolite was hydrothermally synthesized from Beta zeolite with the presence of TMAdaOH and additional silica. The conversion process involved decomposition of 5MRs into 4MRs and 6MRs, rearrangement into D6Rs, and crystallization into SSZ-13 zeolite. The calcined SSZ-13 zeolite prepared from Beta zeolite exhibited slightly lower surface area and pore volume, but stronger acidity compared to the sample from amorphous raw materials.

Summary: Amine modified pumice-derived silica aerogel (AMPDSA) was synthesized and grafted with (3-amino-propyl) triethoxysilane to enhance its adsorption capacity for cefixime antibiotic. Response surface methodology was used to optimize the adsorption conditions, and various kinetic and isotherm models were evaluated for their fit with the batch sorption system. Fixed-bed column experiments were conducted to investigate the effects of flow rate, initial concentration, and bed height on the adsorption capacity. SEM, BET, and XRD characterization confirmed the regeneration ability of the material.

Summary: The aggregation kinetics of colloidal silver and silver iodide nanoparticles during ozone/ultraviolet oxidation were investigated in this study. The results showed that temperature, pH, and initial concentration of nanoparticles had an impact on the aggregation rate and stability of the nanoparticles. Acidic conditions led to faster aggregation due to the neutralization of the negative surface charge of the nanoparticles. Additionally, the type of interaction between ozone/ultraviolet and the nanoparticles' surfaces, as well as the thickness of the electrical double layer surrounding the nanoparticles, influenced the aggregation rate differently for each type of nanoparticles. Colloidal silver nanoparticles followed a diffusion-limited regime, while an intermediate regime between diffusion- and reaction-limited was observed for silver iodide nanoparticle aggregation.

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: A pH-sensitive nanoplatform, PEGylated Zeolitic Imidazolate Framework-8 (ZIF-8/PEG), was used to modulate the cytotoxicity of arsenic polyoxotungstate (K6As2W18O62, KAW). The nanoplatforms showed high loading content and pH-responsive release of KAW. In vitro cytotoxicity experiments demonstrated that the designed nanoplatforms exhibited higher potency against breast cancer cells with lower side effects compared to free KAW.

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: 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: Airlift reactors (ALRs) and airlift bioreactors (ALBRs) have been widely used in various sectors, but there is a lack of comprehensive study on their environmental applications. This article reviews the classification of ALRs, a causal diagram, and a generalized relation of hydrodynamic variables affecting mass transfer coefficient. It also evaluates new configurations of these reactors along with various technologies for water and wastewater treatment, air purification, petroleum desulfurization, waste recycling, and valorization. The efficient treatment of high-strength wastewater, shortened microorganism retention time, liquid circulation, and mixing are enabled by ALRs, while the synergistic action of ozone and other processes allows for effective removal of hard-to-biodegrade organic substances.

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.
