Abstract
Prisutnost faramceutika u vodenom okolišu može nepovoljno utjecati na okoliš i zdravlje ljudi. Cilj ovog rada jest ispitati mogućnost korištenja pepela nastalog izgaranjem petrol koksa za uklanjanje veterinarskog farmaceutika enrofloksacina (ENRO) iz vodenih otopina. Ispitan je utjecaj vremena kontakta otopine enrofloksacina i pepela, temperature i početne koncentracije enrofloksacina. Primijenjeni su dvoparametarski modeli izotermi linearna (Henry-ev zakon), Langmuirova i Freundlichova izoterma korištenjem linearne regresijske analize. Najbolje slaganje eksperimentalnih podataka postignuto je s linearnom (Henryev zakon) izotermom. Utvrđeno je da sorpcija slijedi kinetički model pseudo drugog reda. Vrijednosti termodinamičih parametara (ΔG°, ΔH° i ΔS°) za sustav enrofloksacin-pepeo pokazuju da je proces sorpcije endoterman i spontan. Dobiveni rezultati pokazuju da se pepeo nastao izgaranjem petrol koksa može koristiti kao učinkovit sorbens za uklanjanje enrofloksacina iz vodenih otopina.
Abstract (english)
The presence of pharmaceuticals in aquatic environment poses potential human health and ecological risks. The objective of this work is to examine the adsorption of enofloxacine (ENRO) from aqueous solution using ash from combustion of petroleum coke as alternative adsorbent. The influence of contact time, temperature, and initial enrofloxacine concentration on adsorption performance were experimentally verified by a batch method. Two-parameter isotherm models namely linear (Henry’s law), Langmuir and Freundlich were applied to describe the adsorption process using linear regression analysis. The linear (Henry`s law) isotherm was the best-fit sorption isotherm model for the experimental data obtained. Sorption followed pseudo second-order kinetics. Thermodynamic parameters (ΔG°, ΔH° and ΔS°) were evaluated for the enrofloxacine-zeolite system, which revealed that the sorption process is egzothermic and spontaneous in nature. The findings indicate that petroleum coke ash is a promising adsorbent for the removal of enrofloxacine from aqueous solution.
