Sažetak
Environmental pollution with various pharmaceuticals is becoming serious global issue. When various chemicals are released into environmental waters above capacity for their removal they disturb the ecosystems of flora and fauna in both, water and (indirectly) in terrestrial ecosystems. For instance, pharmaceutical compounds as tolperisone (TLP) are toxic for waters, especially for plants and should be removed from environment. One promising option for water purification is heterogenous photocatalytic degradation with different photocatalysts. Consequently, this research employed the photodegradation of the TLP with two photocatalysts, TiO2 and ZnO under simulated solar and UV irradiation. Evaluated parameters included optimal catalyst loading, length of irradiation, type of light, and degradation of TLP was monitored by the UFLC-DAD and LC–ESI–MS. Environmental toxicity of TLP in plants was examined with wheat evaluating germination, biomass production and photosynthetic pigments of the plant. Chemometric analysis was used to evaluate experimental relations in results. Data showed that the best removal of TLP was with TiO2, at optimal catalyst loading of 1.0 mg/cm3 after 60.83 min of irradiation under UV light. Moreover, it was detected that germination, biomass production, and chlorophyll b (Chl b) were not related with percentage of TLP after irradiation. Whereas, chlorophyll a (Chl a) (r=-0.61, p≤0.05), Chl a+b (r=-0.56, p≤0.05), and carotenoid (car) (r=-0.57, p≤0.05) were strongly inversely (negatively) correlated with TLP concentration, while Chl a+b/car (r=0.36, p≤0.05) was moderately (positively) related.
