Abstract
Sve učestalija upotreba farmaceutika rezultira povećanjem njihovih koncentracija u okolišu. Zbog toga se farmaceutici nazivaju tzv. novim onečišćivalima i dodani su na "watch listu" zajedno s drugim tvarima čije koncentracije će se pratiti u budućnosti. Iz toga proizlazi potreba za razvojem odgovarajućih metoda za obradu otpadnih voda opeterćenih farmaceuticima i njihovim metabolitima. Kao pogodno rješenje pokazuju se tzv. napredni oksidacijski procesi (eng. Advances Oxidation Processes). Cilj provedbe ovog rada bio je određivanje optimalnih uvjeta provedbe UV-A/TiO2 procesa pod simuliranim sunčevim zračenjem kod kojih se postiže najviši stupanj uklanjanja i razgradnje modelnog onečišćivala diklofenaka (DCF). Procesni parametri sustava (početna pH vrijednost, masena koncentracija TiO2) procijenjeni su kombinacijom statističkog i empirijskog pristupa. Za razvoj eksperimentalnog plana primijenjen je puni faktoski plan eksperimenata (FFP). Utvrđeno je da se najveći stupanj razgradnje diklofenaka postiže pri pH=6 i masenoj koncentraciji TiO2 od 2g/l. U sklopu ovog rada razvijen je i matematički model koji zadovoljavajuće opisuje promatrani sustav.
Abstract (english)
Growing use of pharmaceuticals results in an increase in their concentration in the environment. Therefore, pharmaceuticals are called "New pollutants" and they have been added to the "watch list" along with other substances whose concentration will be monitored in the future. This leads to the need for the development of appropriate wastewater treatment methods for pharmaceuticals and their metabolites. Advanced oxidation processes (AOP) are proving to be a suitable solution for the problem. The aim of this paper was to determine the optimum conditions for the implementation of the UV-A/TiO2 process under simulated solar radiation to achieve the highest degree of removal of diclophenac (DCF) in water. The process parameters of the system (initial pH value, mass concentration of TiO2) were estimated by a combination of statistical and empirical approaches. Full factorial experiment plan (FFP) was used to develop the experimental plan. It was found that the highest degree of degradation of diclofenac was achieved at pH 6 and a TiO2 concentration of 2 g/l. As part of this paper, a mathematical model has been developed that satisfies the observed system.
