The accelerating buildup of plastic waste, especially styrene foam, has become a major environmental problem. Traditional methods recycling do not help in managing Styrofoam waste efficiently because economic factors and minimal technological advancements available. Pyrolysis is one the promising ways to transform styrenofoam wastes into value-added compounds with nominal emission harmful gases. This research aims explore synthesis graphene quantum dots (GQDs) from through hydrothermal pyrolysis convert it high-utility, product. successful formation GQDs was confirmed multiple characterization techniques: transmission electron microscopy revealed uniform size distribution 6 ± 1 nm; dynamic light scattering all GQD samples were below 10 Raman spectroscopy identified presence single-layered structure; X-ray photoelectron demonstrated incorporation nitrogen oxygen functionalities. yield increased increase reaction temperature edge functionalities, giving peak value 1.87 as using photoluminescence UV-Vis spectroscopy, indicating their suitability for enhanced optical performance. synthesized explored sensors detection heavy metal ions water. sensor showed versatility efficacy copper across different pH levels, water sources, anions present various salts. Ultimately concentration unknown ion solutions calculated GQD-sensor-based RGB studies, matching closely values solutions. work demonstrates approach pyrolysis-based treatment contributing management sustainability efforts.
