A new green hydrogel consisting of cherry stone (CS) powder and sodium alginate (SA) was synthesized through physical crosslinking. The product had a mean diameter 3.95 mm, moisture content 92.28%, bulk density 0.58 g/cm3, swelling ratio 45.10%. analyses its morphological structure functional groups by scanning electron microscopy (SEM) Fourier-transform infrared spectroscopy (FTIR) showed the successful entrapping CS in SA polymeric matrix. viability prepared as adsorbent tested towards Orange II (OII) anionic dye. influence pH, amount, contact time, initial dye concentration evaluated. Then, impact three accelerating factors (stirring speed, ultrasound exposure duration, temperature) on OII retention investigated. highest recorded removal efficiency adsorption capacity were 82.20% 6.84 mg/g, respectively. followed Elovich pseudo-second-order kinetics, adequately described Freundlich Khan isotherms, can be defined spontaneous, endothermic, random. experiments confirmed that obtained used acceptably for at least two consecutive cycles, sustaining effectiveness water decontamination.

This study investigates the efficacy of activated carbons (ACs) derived from Tamarix gallica (TG) leaves for glyphosate removal aqueous solutions. Two chemical activation methods, using phosphoric acid (H3PO4) and sulfuric (H2SO4), were compared to optimize adsorbent performance. The resulting materials, labeled AC-H3PO4 AC-H2SO4, comprehensively characterized XRD, FTIR, SEM-EDS, BET analysis, pHpzc determination, revealing distinct physicochemical properties. exhibited a larger surface area (580.37 m2/g) more developed pore structure AC-H2SO4 (241.58 m2/g). Adsorption kinetics best described by pseudo-first-order model both adsorbents. Isothermal studies demonstrated that followed pore-filling mechanism Dubinin–Radushkevich model, while showed multilayer adsorption fitting Freundlich model. Both adsorbents high capacities, with maximum Langmuir capacities 247.58 mg/g 235.13 respectively. mean free energy (E) values confirmed physisorption as dominant mechanism. research highlights potential TG-derived sustainable effective remediation in water treatment applications, demonstrating impact methods on

The escalating prevalence of emerging contaminants, notably pharmaceutical and personal care products (PPCPs), poses a significant threat to global freshwater reservoirs, environmental equilibrium, human well-being. Trace amounts these micropollutants persist within aquatic environments, posing challenges in their detection, analysis, wastewater remediation using conventional approaches. Enhanced tertiary treatments (ETTs), encompassing methods such as adsorption on activated carbon (AAC), advanced oxidation processes (AOP), membrane separation process (MSP), have been introduced address challenges. This review underscores the pressing necessity for economical efficacious alternatives, with particular focus polymeric technology membrane-based treatment. approach demonstrates cost-effectiveness, facile production, excellent pollutant selectivity. Furthermore, paper explores viability utilizing agricultural waste an alternative adsorbent material adsorption-membrane hybrid systems. Introducing innovative approach—adsorption-membrane waste—this advances beyond existing literature. By leveraging alongside unique attributes adsorbents, this strategy aims enhance efficacy Noteworthy its comprehensive exploration precursors derived from waste, presents novel promising avenue treatment advancement.

This study presents effective methods for utilizing the TiO2 photocatalyst in environmental remediation, with a particular focus on removal of carbofuran pesticide (CBFP) from wastewater. Silver (Ag) was selected as potential dopant to improve optical properties well electron-hole pair separation efficiency TiO2. Ag-doped (Ag-TiO2) effectively decomposed 92.8% CBFP under solar light, which significantly higher than that (21.3%). Ag-TiO2 also exhibited good reusability degradation, reduction less 3% after three cycles. In practical applications, successfully degraded 89.3% wastewater and 98.7% surface water. The findings this work bring an method removing pollutants using photocatalyst.
