Abstract
Cilj ovog rada bio je ispitati mogućnost primjene modificiranog pivskog tropa kao jeftinog biosorbensa za uklanjanje kongo crvenila iz vodenih otopina adsorpcijom. Šaržni adsorpcijski eksperimenti provedeni su s ciljem ispitivanja utjecaja koncentracije bojila (10, 20, 30, 40, 50, 100, 150, 200 mg/L), pH vrijednosti (4-10), masene koncentracije biosorbensa (1 do 10 g/L) te vremena adsorpcije (3 do 360 min). Povećanjem masene koncentracije adsorbensa, raste i postotak uklanjanja kongo crvenila te je najveći postotak uklanjanja kongo crvenila iznosio 92,49 %. Pri pH 5, postotak uklanjanja kongo crvenila bio je najveći (93,75 %) te rezultati ukazuju na to da je pH značajno utjecao na adsorpciju kongo crvenila. Osim toga, uočeno je kako se bojilo brže uklanja tijekom prvih 60 minuta, nakon čega se adsorpcija usporava i uspostavlja ravnotežno stanje. Pri manjim početnim koncentracijama bojila, adsorpcija je bila učinkovitija.
Abstract (english)
The aim of this paper was to examine the possibility of utilizing modified brewer’s spent grain as cheap bioadsorbent for removing Congo red from aqueous solutions by adsorption. Batch experiments were carried out to investigate the effect of dye concentration (10, 20, 30, 40, 50, 100, 150, 200 mg/L), pH value (4-10), adsorbent mass (1-10 g/L), contact time (3-360 minutes). By increasing the adsorbent mass concentration, removal percentage of Congo redwas 92,49%The maximum Congo red removal was at pH 5 (93,75%), and the results indicate that the pH have a significant effect on the adsorption of Congo red. In addition, it was observed that the dye was removed faster during the first 60 minutes, after which the adsorption slows down. At lower dye concentration the adsorption was more efficient.
