Abstract
Farmaceutici u okolišu, tzv. "nova zagađivala", zaokupljaju pozornost znanstvenika zbog spoznaje o njihovoj potencijalnoj opasnosti i negativnim učincima na cjelokupni živi svijet. Porastom proizvodnje i potrošnje farmaceutika na globalnoj razini raste njihova koncentracija u okolišu, a samim time i opasnost po okoliš u cjelini. Konvencionalne metode obrade industrijskih i komunalnih otpadnih voda su često nedovoljno učinkovite, stoga je njihova primjena u svrhu uklanjanja farmaceutika ograničena. U tom slučaju, kao alternativa se nudi primjena naprednih oksidacijskih procesa za uklanjanje farmaceutika i drugih organskih onečišćivala iz otpadne vode. U ovom radu ispitana je mogućnost razgradnje diklofenaka u vodi primjenom heterogenog procesa Fentonovog tipa. Sintetski zeolit ZSM5-tipa modificiran je željezom i korišten kao katalizator u UV-A/FeZSM5/H2O2 procesu. Nizom eksperimenata ispitivan je utjecaj pH vrijednosti, koncentracije željeza i koncentracije vodikovog peroksida na mineralizaciju diklofenaka. Dizajn eksperimenta ostvaren je primjenom Box-Behnken-ovog plana i metode odzivnih površina. Utvrđeni su optimalni uvjeti UV-A/FeZSM5/H2O2 procesa: pH = 4, [Fe] = 2 mM i [H2O2] = 50 mM. Ispitana je i kinetika procesa uklanjanja diklofenaka pri optimalnim uvjetima analizom uzoraka u različitim vremenima trajanja reakcije. Također, određivani su i ekološki pokazatelji kvalitete obrađene vode, tj. kemijska potrošnja kisika, biokemijska potrošnja kisika te toksičnost na Vibrio fisscery.
Abstract (english)
Pharmaceuticals in the environment, so called „emerging contaminants”, have drawn attention of scientists because of growing awareness about potential negative impacts of pharmaceuticals to the entire environment. Production and usage of pharmaceuticals on a global scale is steadily increasing and so is their concentration in the environment. Conventional wastewater management methods have often proven to be insufficiently effective, therefore their application for pharmaceuticals removal is often limited. Advanced Oxidation Processes (AOPs) stand as an promising alternative to remove pharmaceuticals and other organic pollutants from effluents. In this research, the capability of a heterogeneous Fenton-type process for degradation of diclofenac in water was investigated. The synthetic zeolite ZSM5-type was modified with iron and used as a catalyst in UV-A/ZSM5/H2O2 process. By a series of experiments the influence of pH, concentration of iron and hydrogen peroxide on mineralization of diclofenac was examined. For the design of experiments, the Box-Behnken's plan and response surface methodology were applied. The optimal conditions of UV-A/FeZSM5/H2O2 process were defined, pH = 4, [Fe] = 2 mM and [H2O2] = 50 mM. Diclofenac conversion kinetics in optimal conditions was examined by sample analysis in various reaction times. Also, ecological quality indicators of processed water, i.e. chemical oxygen demand, biochemical oxygen demand and toxicity on Vibrio fisscery were determined.
