  Abstract

Plastic manufacturing is increasing due to its advantages (low cost, durability, water-proof property) to various application fields such as agriculture, electronics, medical equipment, and others. At the same time, despite recyclability of plastics, byproducts of plastics are ever increasing resulting in the generation of secondary microplastics (MPs; less than 5 μm in size) caused by various environmental and physicochemical factors. Although pretreatment of MPs was studied due to the hazardous effect of MPs to the ecosystems, chemical effects of agents on the MPS used in the pretreatment were not deeply studied. In this study, the chemical effect of acid, alkali, and oxidizing agent on the PVC based MPs was studied. The PVC MPs were reacted with acids, alkalis, and oxidizing agent at 70 °C for 7 days, and changes of morphologies and chemical properties were observed when PVC MPs were reacted with sulfuric acid. The results pertaining to the chemical variations of PVC MPs could be a foundation stone for future research related to the pretreatment of MPs with various chemical agents.
