3D printed polyvinyl alcohol ferrate(VI) capsules: Effective means for the removal of pharmaceuticals and illicit drugs from wastewater

Popis výsledku v původním jazyce

Wastewaters are considered as a significant source of pathogenic microorganisms and wide spectrum of various compounds. In this study the capsulation of ferrate using 3D printing and its application for the degradation of selected pharmaceuticals, illicit drugs and its metabolites in real wastewater from the effluent of urban wastewater treatment plant (WWTP) Petrzalka and Psychiatric clinic was investigated. In the first part of the study, the stability of capsules made from various polymeric materials was tested. The best results were found in the case of the laboratory 3D-printed polyvinyl alcohol (PVA) capsules where high long-term stability of ferrate was observed. In this type of capsules ferrate can be stored at ambient conditions more than one month without significant decrease of its degradation efficiency. In the next part of the study the ability of ferrate capsulated in 3D printed PVA capsules to oxidize various micropollutants present in real wastewater was tested. The best efficiency was achieved for clarithromycin, azithromycin, valsartan, diclofenac, atenolol and carbamazepine (over 80%). However, some of the tested compounds, such as caffeine, tramadol, and venlafaxine were only partially oxidized. It was also found that an increase of the amount of capsulated ferrate did not always lead to a significant increase of degradation efficiency. Capsulation of ferrate used in our research gives, therefore, the possibility not only to store but also to instantly apply ferrate in emergency situations and even in those environments where pure ferrate is rapidly decomposed.
