| Abstract |
The problem of microplastic has recently emerged as the worldwide use of plastics has increased. Although many studies are being conducted to address the microplastic problem, the impact is still insignificant and takes a long time. Therefore, in this study, microplastic degradation studies were conducted according to the amount of particles injected using dielectric barrier discharge that can efficiently decompose microplastic particles. As a result, after 120 minutes of treatment at 0.05 g input, the removal efficiency reached 5.44%, and the carbonyl index (CI) was 1.7308. In addition, the smaller the amount of injected particles, the higher the removal efficiency and CI. However, when considering the absolute removal amount and energy yield, it was necessary to design an appropriate input amount according to the characteristics of the dielectric barrier discharge (DBD) device. This study's findings should be useful for future research on microplastic degradation using DBD techniques. |
