Bacteriopheophytin a showed significantly higher photostability in comparison to bacteriochlorophyll a for all applied irradiation treatments, for about one to three orders of magnitude.

SEM micrographs demonstrated agglomerated particles of Clinoptilolite with no changes in particles, but with increased porosity for Clinoptilolite modified at 300 and 400 oC. The content of elements is lower in thermally modified Clinoptilolite at higher temperatures (300 and 400 oC) than for clinoptilolite treated at 120 oC. After the extraction, EDX analysis of clinoptilolite adsorbed BaP, showed the increased percentage of carbon in the modification prepared at 300 oC, indicating the structure of the applied sorbent is more suitable compared to one treated at 400 oC.

The only observed qualitative difference was related to the presence of vanillic acid. Extract of A. alba from Rosomač was richer in phenolic compounds and flavonoids than A. alba from Mojinci. The extract of A. alba from Rosomač also possessed higher antioxidant capacity than A. alba from Mojinci, which was especially noticed in the 2,2-diphenyl-1-picrylhydrazyl assay.

The first preparation method consists of digestion with 18.5% HCl, and the other method is the digestion with aqua regia. Regarding the extraction of some secondary nutrients and micronutrients (Ca, Mg, Fe, Mn, Cu, Zn, and B) from NPK fertilizer, better extraction was achieved using the first method for B, Ca, and Mg, while the other method was better for Fe, Mn, Cu, and Zn.
