20.500.12556/RUL-168398 Surface properties of microalgal biomass and microplastics exploring point of zero-charge and contact angle The surface properties of microalgal biomass and microplastics, focusing on the point of zero charge (PZC) and water contact angle (CA), were investigated. Microalgae, particularly Chlorella vulgaris and mixed microalgal consortia, were cultivated and analyzed for their surface characteristics. Oven-dried and freeze-dried samples exhibited varying degrees of hydrophilicity, with freeze-dried microalgal consortia exhibiting more hydrophilic surface. The PZC values indicated a higher density of negative charges on the surface of C. vulgaris compared to the microalgal consortia biomass. Microplastics (MPs)from agricultural mulch films, including biodegradable and non-degradable types, were also examined. Results showed that naturally aged MPs exhibited more hydrophilic surfaces compared to their pristine counterparts. The PZC values of microplastics varied, with some showing neutral to slightly negative charges at environmental pH levels. The findings underscore the importance of surface characterization in understanding the sorption mechanisms of contaminants. microplastics microalgal biomass surface properties point of zero-charge water contact angle sorption true false true Angleški jezik Ni določen Znanstveno delo 2025-04-11 11:38:19 2025-04-11 11:38:20 2025-04-12 04:11:17 0000-00-00 00:00:00 2025 0 0 Str. 24-31 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 502.131.1 10.55295/PSL.12.2025.II2 232274435 228834307 2+Sunta+Urska.pdf 2+Sunta+Urska.pdf 1 CFE97C1DD489DFD5298237DC84327645 9de4acaae7831125576305af06f97246aaf8cd23e637d0d50e4844d38009bb54 3d708d99-16b8-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201787 https://ebooks.uni-lj.si/ZalozbaUL/catalog/view/742/1126/11429 1 a6f6dc2e-16b7-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201786 Zdravstvena fakulteta 0 0 0
