Özet
Plastic materials such as polyethylene (PE), polyvinyl chloride (PVC), and polyamide nylon 6 (PN6) are extensively used worldwide. Significant quantities end up in the environment as waste, which gradually deteriorate and may travel for long distances. In this study, the capacity of these microplastics to sorb RR 120, an anionic dye commonly found in textile wastewaters, was investigated. PN6 showed the highest sorption capacity of 4.80 mg g?1, at a dose of 0.4 g and pH 2, whereas increasing the dose of the microplastic resulted in a gradual decrease of the sorption capacity for all materials. Increasing the dye concentration, resulted in higher sorption capacities. The FTIR analysis of the microplastics before and after sorption of RR 120, indicated no chemical bonding pointing out the absence of covalent bonds with specific surface groups of the microplastics in the sorption of RR 120. A plausible explanation for the highest sorption capacity of PN6 is the presence of N and O, which can readily form H bonds with the hydroxyl groups of RR 120.
