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.

Frequent use of pesticides results in the release large quantities their residues environment, raising various concerns for humans and ecosystem. This work introduces a simple cost-effective method removal atrazine pesticide residue (APR) from agricultural wastewater using Cu doped-ZnO photocatalyst (Cu-ZnO). The modification ZnO with significantly improved its optical photoelectrochemical properties, band gap narrowing 3.3 to 2.64 eV. photodegradation APR was 93.6 91.7% aqueous solution wastewater, respectively. After being reused four times, Cu-ZnO did not display notable drop degradation performance, rates 93.6, 91.2, 86.8, 83.1% during first, second, third, fourth recycles, Also, after six cycles <2%, suggesting excellent stability modified without any issues related secondary pollution. Under natural sunlight, 83.9% removed, confirming benefit reducing treatment costs by utilizing renewable energy. In addition, mechanism proposed based on outcomes radical quenching TOC tests.
