Summary: In this study, bio-based adsorbents in the form of macroporous sponges were prepared through freeze-drying of a chitosan solution and water hyacinth fiber. The addition of genipin as a crosslinker improved the sponges' resistance to compression, water, and thermal stability. The composite sponges showed excellent adsorption capacities for removing C.I. reactive orange 16 from water, following Freundlich isotherm and pseudo-second-order kinetics models. Furthermore, the sponges could be reused for multiple cycles.

Summary: Water contamination is a growing global issue, and current methods for water and wastewater treatment are limited, especially in terms of difficult regeneration of fossil-fuel derived nano-adsorbents. Advanced methods using sustainable materials like chitosan are needed. Chitosan, a biopolymer extracted from shellfish, is non-toxic, abundant, and chemically stable. It can be shaped into various forms for wastewater treatment. In this review, we focus on chitosan-based beads and their applications in wastewater treatment, including adsorption mechanisms, pollutant removal, functionalization, and regeneration. Notably, chitosan/Fe-hydroxyapatite beads have high adsorption capacity for lead removal, while imprinted magnetic chitosan beads show good reusability for nickel removal.

The highest percentage of certain compounds was observed at 150 mg/l and 100 mg/l of functionalized carbon nanotube. Overall, the use of functionalized carbon nanotubes as a stimulant increased the antioxidant capacity and secondary metabolite content of basil.

Summary: Industrial wastewater is a major source of pollution due to its close proximity to bodies of water and the presence of microplastics. This research provides insights into the fate of microplastics in industrial wastewater treatment plants (WWTPs) worldwide and explores the effectiveness of advanced treatment technologies in eliminating microplastics. The continuous presence of microplastics in various ecosystems, their adsorption of pathogens and toxic substances, and potential risks to aquatic life and human health make microplastics a growing concern. This work critically evaluates current and developing techniques for microplastic detection and removal in industrial wastewater, aiming to establish a waste disposal standard that minimizes the hazardous effects of microplastics in aquatic systems.

Summary: The occurrence of arsenic in water is a global public health problem, and adsorption onto iron oxy-hydroxides is a commonly used technique for its removal. This study investigated the combined use of graphene oxide (GO) and granular ferric hydroxide (GFH) in different molar ratios for maximum As(III) removal. The presence of GFH enhanced the adsorption capacity of GO, with the optimal molar ratio of GO/GFH 2:1 achieving 90% removal at pH 7.0 +/- 0.1. The Freundlich isotherm and pseudo-second-order kinetic models effectively described the experimental data, with a maximum adsorption capacity of 22.62 μg/g.

Summary: Heavy metals are important pollutants that pose a threat to the aquatic environment. Different fish species have varying levels of metals and metalloids, influenced by factors such as geographical location. Through analyzing fish samples from different countries, it was found that Capoeta umbla and Ctenopharyngodon idella in Turkey had the highest concentrations of chromium and arsenic, respectively. Guinea's Penaeus notialis had remarkably high levels of arsenic. With the exception of Amblyceps mangois from Bangladesh, cadmium concentrations were generally low in fish. Plectropomus pessuliferus and Epinephelus summana in Jeddah, Saudi Arabia exhibited extremely high levels of lead. Mercury content in fish was mostly within permissible limits.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
