Nonylphenol Removal from Water and Wastewater with Alginate-Activated Carbon Beads

Separations, Год журнала: 2025, Номер 12(5), С. 103 - 103

Опубликована: Апрель 22, 2025

In this study, eco-friendly and sustainable alginate-activated carbon (Alg-C)-based beads were synthesized characterized for the adsorption of nonylphenols (NPs) from aqueous environments under various conditions. The surface characterization, functional groups, behavior analyzed using multiple analytical techniques. effect key parameters, including dosage, pH, temperature, reusability, evaluated. Isotherm kinetic studies revealed that process followed a pseudo-second-order model aligned with Freundlich isotherm, indicating heterogeneous surface. exhibited high removal efficiency 97% over five reuse cycles in 50 mL solution 10 mg L−1 NPs static conditions, demonstrating their recyclability. Thermodynamic analysis suggested potential electrostatic interactions, supported by positive Gibbs free energy values. highest performance was achieved within 90 min, capacities 0.10 to 0.39 g−1. Additionally, Alg-C remained stable across different pH levels, highlighting robustness. When tested wastewater samples, maintained efficiency, no significant matrix effects observed. These results underscore as promising elimination contaminated water sources.

Abstract TiO 2 is the most widely used photocatalyst owing to its advantages, such as exceptional surface area, stability, and high activity. However, suffer from a wide band gap recombination rate of charge carriers. This research assesses knowledge structure various strategies adopted modify titanium dioxide (TiO ) for wastewater remediation. Capitalizing VOSviewer software, bibliometric analysis was performed on 898 articles extracted Web Science (WoS) database determine intellectual collected documents. Three major clusters were generated through bibliographic coupling four co-occurrence analysis, which emerging future trends modification approaches determined, respectively. Bibliographic highlighted three key -modification technique. The revealed that current focus utilization copper-based dopants in , demonstrating improved isolation visible light activation. second cluster underscores noble metal doping, with gold silver compounds leveraging localized plasmon resonance (SPR) properties. third explores graphene-based co-doping strategies. Co-occurrence 56 high-frequency keywords thematic centres nanocomposites pollutant treatment, integration adsorption, photocatalysis advanced thin-film deposition techniques. significance this study lies potential guide researchers exploring identified nanocomposite materials techniques enhance efficiency properties photodegradation organic molecules wastewater.
