Abstract
Pojava novih onečišćivala, posebice mikroonečišćivala, izaziva zabrinutost zbog potencijalne štetnosti po okoliš. Konvencionalne metode nisu učinkovite za njihovo potpuno uklanjanje te se istražuju nove, poput naprednih oksidacijskih procesa. Kao glavni preliminarni proces u obradi voda koristi se proces adsorpcije onečišćivala na adsorbat. U ovom je radu ispitana adsorpcija farmaceutika tobramicina (TB), etodolaka (ETD) i donepezil hidroklorida (DPH) te pesticida diurona (DIU) na adsorbens TiO2-P25. Ispitivanje fizikalno-kemijskih interakcija otopina provodilo se pri pH vrijednostima 4 – 10 i koncentracijama TiO2-P25 koje su iznosile 0,4 g L^-1 - 1,2 g L^-1, dok su procesne temperature iznosile 15 ºC - 35 ºC. Za opisivanje adsorpcijske ravnoteže korištene su Langmuirove i Freundlichove izoterme. Eksperimentalni rezultati ukazuju da se kinetika adsorpcije odvija prema reakcijama pseudo-drugog reda. Navedene izoterme su se pokazale neadekvatnima za opisivanje adsorpcijskih procesa, dok je ispitivanjem termodinamike utvrđeno da su provedeni adsorpcijski procesi spontani i egzotermne prirode.
Abstract (english)
The emergence of new pollutants, especially micropolutants, raises concerns about potential environmental damage. Conventional methods are not effective for their complete removal and new ones, such as advanced oxidation processes, are being investigated. The process of adsorption of pollutants on the adsorbate is used as the main preliminary process in water treatment. In this work, the adsorption of the pharmaceuticals tobramycin (TB), etodolac (ETD) and donepezil hydrochloride (DPH) and the pesticide diuron (DIU) on the adsorbent TiO2-P25 was investigated. Examination of physico-chemical interactions of solutions was performed at pH values 4 – 10 and TiO2 concentrations of 0.4 g L^-1 – 1.2 g L^-1, while process temperatures were 15 ºC – 35 ºC. Langmuir and Freundlich isotherms were used to describe the adsorption equilibrium. Experimental results indicate that the adsorption kinetics proceed according to pseudo-second order reactions. These isotherms proved to be inadequate for describing adsorption processes, while thermodynamic testing revealed that the performed adsorption processes were spontaneous and exothermic.
