Tin disulfide has been the focus of several investigations on its applicability in various fields due to exceptional qualities. Furthermore, while there are studies adsorption properties, is a research gap effects incorporation into biopolymer matrix characteristics. In this study, experimental removal methylene blue (MB) dye from wastewaters by eco-friendly, low-cost and method using SA/SnS2 composite adsorbents filled with SnS2 were carried out performances evaluated. The characterized FTIR-ATR, SEM-EDX, XRD. It was observed that capacity increased 219.17 ± 5.36 mg/g 399.65 5.89 increasing mass percentage composition best adsorbent SA/SnS2/30. From isotherm models, Langmuir Temkin models found be most compatible for 𝑞𝑚 value SA/SnS2/30 determined as 532.52 6.67 at 318 K model. also about two times higher than adsorbent. process follow an Elovich quasi-second-order kinetic models. Thermodynamic parameters showed MB endothermic (Δ⁢𝐻𝑜=11.37±0.09 kJ/mol) spontaneous (Δ⁢𝐺𝑜=−25.24±0.28kJ/mol 298 K) Considering all results, can used environmentally friendly, biodegradable, sustainable, effective, reusable aqueous solutions.

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.
