Abstract	Ovim radom istraživana je optimizacija razgradnje prirodnih organskih tvari postupkom UV/ H2O2 pomoću faktorskog plana pokusa i metode odzivne površine. Istraživanje se provodilo na modelnoj vodi te se pratio utjecaj promjene sadržaja otopljenog organskog ugljika i doze vodikovog peroksida na stupanj uklanjanja otopljenog organskog ugljika pri konstantnoj pH vrijednost. Faktorskim planom pokusa ispitan je plan glavnog pokusa, a metodom odzivne površine su se prikazali rezultati procesa. Za analizu rezultata koristio se programski paket Design Expert 7. Dobivenom regresijskom funkcijom modela prikazani su rezultati maksimalnog uklanjanja otopljenog organskog ugljika. Prema rezultatima, pri sadržaju otopljenog organskog ugljika od oko 8 mg/L te uz primjenu doze H2O2 od približno 250 mg/L postignuta je maksimalna razgradnja od oko 34%.
Abstract (english)	The purpose of this study was to investigate the optimization of natural organic matter degradation by UV/H2O2 process using a factorial design of experiment and a response surface method. The research was performed on model water and the influence of variable concentration of dissolved organic carbon and hydrogen peroxide dosage on the removal degree of dissolved organic carbon at a constant pH was investigated The process was optimized by design of experiment and response surface methodology. Design Expert Software version 7 was used for developing and evaluating the experimental design. According to the results, with a dissolved organic carbon concentration of around 8 mg/L and hydrogen peroxide dosage less than 250 mg/L, the maximum degradation of about 34 % was achieved.
