Abstract
This study addresses the challenge of removing the persistent mycotoxin deoxynivalenol (DON) by employing kaolin-group minerals - natural halloysite (HD), purified halloysite (HS), and synthetic kaolinite nanotubes (MNC) - as supports for TiO2, Fe2O3, and TiO2/Fe2O3 semiconductors. The nature of the mineral support strongly influenced the dispersion and size of the loaded semiconductors, leading to the formation of highly dispersed nanosized active particles, particularly on the MNC surface. In the presence of potassium peroxymonosulfate (PMS), TiO2-containing composites achieved up to 97.7% DON removal within 20 min under UV irradiation, while Fe2O3 showed higher activity under visible light. Among the composites, the MNC support loaded with TiO2/Fe2O3 exhibited the highest DON removal, which correlated with more efficient electron transfer and reduced charge transfer resistance, indicating improved interfacial charge transport. Scavenger and EPR analyses suggested that PMS activation followed electron-transfer pathways, in which initially formed SO4•– radicals underwent rapid hydrolysis to yield •OH, identified as the dominant reactive species in aqueous solution, with an additional contribution from 1O2. UHPLC-ESI-MS/MS analysis indicated that DON degradation was initiated by oxidative transformation of key functional groups, including epoxide ring opening, followed by progressive fragmentation of the trichothecene structure, with pathways dependent on catalyst composition.
