Green nanotechnology has gained attraction in recent years due to the growing awareness of environmental and health risks associated with traditional methods nanomaterial synthesis. In present study, nanocomposite (NCs) silver Iron were prepared using Zanthoxylum Armatum seeds aqueous extract which acts as a reducing, stabilizing, capping agent. The synthesized NCs characterized UV/Vis Spectroscopy, powder X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), EDX. spectroscopy analysis revealed presence surface plasmonic resonance band occurring at 420 nm. Examination through SEM demonstrated that they exhibited nearly spherical morphology, an average particle diameter measuring 54.8 crystalline nature these was verified calculation crystallite size Scherrer-Debye equation yielded value 12.6 adsorption ability newly nanocomposites investigated against Acid Black 234 Dye. results showed 0.5 g dose pH 4 removed 99.3% 10 mg/L Dye within 60 min. Based on findings this research, it can be inferred Ag-Fe from hold significant potential for addressing pollution caused by used adsorbent removal dye wastewater sample 98% commercial context, research highlights environmentally friendly synthesis nanocrystals (Ag-Fe NCs) mediator offers efficient cost-effective solution mitigating pollution.
