ABSTRACT Heavy metal and dye pollution are significant environmental challenges that seriously threaten human health ecosystem balance. This study introduces a new method for recovering Ag + from wastewater uses the recovered silver secondary catalytic applications in degradation. Polydopamine functionalized polystyrene mesoporous microspheres (PPS‐PDA) were prepared using green mussel chemical based on monodisperse (PPS) with diameter of approximately 7 μm. According to results Brunauer Emmett Teller Analyzer, average pore size PPS‐PDA is 17.88 nm, porosity 0.53%, specific surface area 54.52 m 2 /g. By observing scanning electron microscope energy dispersive spectroscopy, has an adsorption effect ammonia solution can adsorb up 40% solution. The process was monitored by UV–visible light. adsorbed Ag‐supported polydopamine (PPS‐PDA‐Ag) showed strong activity methylene blue reduction, behavior consistent pseudo‐second‐order kinetic model. catalyst maintained efficiency 85% 10 cycles, highlighting its potential sustainable treatment.
