CLAIM research topic: How effective is the photo-Fenton process for degradation of microplastics?

Another impactful study, the ninth publication in CLAIM’s research collection in Frontiers in Marine Science journal, puts its focus on the removal of microplastic from water and investigates the potential threats to sea creatures and their habitat.

The CLAIM researchers from the National Research Council in Genova, Italy, and the KTH Royal Institute of Technology in Stockholm, Sweden, used the photo-Fenton process to study the removal of model microplastics, polypropylene (PP) and polyvinyl chloride (PVC).

The results showed that high degradation efficiency of PP and PVC microplastics was reached in a relatively short time and that after 1 week of irradiation, more than 95% of the average particle volume was reduced.

Another aspect of their study was to understand the environmental impact of the photo-Fenton process of microplastics degradation. This was done through an ecotoxicological approach. An ecosafety screening was carried out utilising a lab scale equipment and a series of studies (bioassays) under controlled settings, assessing water samples following photo-Fenton destruction of microparticles.

The results showed that samples taken before and after the photo-Fenton process had no hazardous effect, indicating that no toxic by-products developed during the degradation process.
