Sažetak
Due to the increasing use of pharmaceuticals in everyday life, there is growing water pollution. Particularly expressed are their increased concentrations in surface, underground and drinking waters that can not be reduced by conventional processing processes. For that reason, advanced oxidation processes (AOPs) can be used because of their effective removal rate of recalcitrant organic compounds. In this paper, removal rate from water for ten pharmaceuticals was measured by two AOP processes: UV/H2O2 and UV/PS. The following pharmaceuticals include desloratadine, desvenlafaxine, donepezil hydrochloride, etodolac, febuxostat, hydrochlorothiazide, memantine hydrochloride, omeprazole, silver sulfadiazine and tulathromycin. Experimental first order pseudokinetics were obtained for different concentrations of oxidant - hydrogen peroxide (H2O2) and sodium persulfate (PS). With the competitive reference compound, para- chlorobenzoic acid (pCBA), the second order rate of pharmaceutical removal was calculated.
