Abstract
As recycling plays a crucial role in environmental sustainability, we investigated the properties of polyamide 6 composites derived from end-of-life vehicles and evaluated the effects of various cleaning agents and conditions. Prior to washing, the chemical composition and surface contaminants of the recycled composites were characterized using a range of analytical techniques. Following the cleaning process, total organic carbon content was measured, and gas chromatography–mass spectrometry (GC–MS) was employed to assess the removal efficiency of volatile organic compounds under different cleaning conditions. The results indicate that cleaning with cetyltrimethylammonium bromide at 70 °C under sonication is the most effective method. Furthermore, GC–MS analysis revealed a significant reduction in the concentrations of benzene, toluene, ethylbenzene, and xylene after washing.These findings suggest that appropriate cleaning treatments enhance material purity and contribute to improved recycling efficiency.
