Sažetak
Plastic, due to its many advantages, is an inevitable material in everyday lives. Production and utilization are growing daily, and consequently, these types of materials are accumulating in the environment. Plastic particles smaller than 5 mm, called microplastics (MP), pose a major threat to aquatic organisms. MP can cause different harmful effects on various organisms.[1] Since classical removal methods are not effective enough, the use of advanced oxidation processes (AOPs) to degrade MP has recently been considered.[2] In this paper, two AOPs were conducted: UV-C/H2O2 and UV-C/S2O82-. Tested MP were polyethylene (PE) and polypropylene (PP), with particle sizes between 25 and 100 µm. The influence of pH value, MP mass, oxidant concentration, and process duration was investigated. The results indicated that UV-C/S2O82- had a greater impact on both used MP.
