Article Abstract

The growing utilization of renewable and residual biomasses for environmental preservation and remediation are important goals to be pursued to minimize the environmental impact of human activities. In this paper, sodium alginate (derived from brown algae) was crosslinked using chitosan (mainly derived from the exoskeleton of crustaceans) in the presence of biowaste-derived substances isolated from green compost (BBS-GC), to produce hydrogels and dried films. The obtained materials were tested as adsorbents for wastewater remediation. To this purpose, gels were characterized using a multi-analytical approach and used as active substrates for the removal of three differently-charged molecules, chosen as model pollutants: crystal violet, rhodamine B, and orange II. The effectiveness of the gel formulations was demonstrated and attributed to the variety of active functionalities introduced by the different precursors, the structural factors and the peculiar physicochemical properties of the resulting materials.

Effective uranium (U) capture is required for the remediation of contaminated solutes associated with the nuclear fuel cycle, including fuel reprocessing effluents, decommissioning, or nuclear accident cleanup. Here, interactions between uranyl cations (UO ) and a Mg-Al layered double hydroxide (LDH) were investigated using two types of uranyl-bearing LDH colloids. The first (ULDH) was synthesized by coprecipitation with 10% of Mg substituted by UO .

Researchers in the field of photocatalysis are interested in finding a solution to the problem of charge transfer and recombination in photodegradation mechanisms. The ideal photoactive catalyst would be inexpensive, environmentally friendly, easily manufactured, and highly efficient. Graphitic carbon nitride (g-CN) and metal oxide (MOx) based nanocomposites (g-CN/MOx) are among the photocatalysts that provide the best results in terms of charge transfer capacity, redox capabilities, and charge recombination inhibition.

With the global implementation of wastewater reuse, accurately assessing the soil ecological risk of chiral pollutants from wastewater necessitates a comprehensive understanding of their enantioselective toxicity to soil animals. Ibuprofen (IBU) is the most prevalent chiral pharmaceutical in municipal wastewater. However, its enantioselective toxicity toward soil animals and the underlying mechanism remain largely unknown.

While technological advancements in treating electroplating wastewater continue, removing high concentrations of Ni and Co remains a challenge. Surface functionalization of clay has emerged as a pivotal approach for effectively removing heavy metals, rivaling intercalation modification in its effectiveness. This study investigated the adsorption performance and mechanisms of a phosphonate-modified layered double hydroxide material, employing batch experiments and simulation calculations to elucidate the impact of surface modification on adsorption behavior.
