dc.description.abstractFluoride ions are increasingly present in the groundwater mainly due to the anthropogenic activity. On the other hand, increased awareness of harmful effects caused by high concentrations of F-in drinking water, leads to severe standards of water quality. Because of this, intensive researches of new methods for fluoride removal from water streams have been made in last decade. This paper examines the potential of aluminum alginate particles as a cheap and efficient biosorbent for F- removal. The adsorbent characterization before and after F- adsorption was performed using FT-IR technique. Adsorption experiments were conducted in a stirring batch mode, varying both concentration of adsorbate and adsorbent dose. Obtained result of 11,40 mg F-/g Al-alginate indicates a high adsorption capacity, while the kinetic parameters show fast removal kinetics.en
dc.description.abstractAntropogeni faktor uslovio je sve veće prisustvo fluoridnih jona u podzemnim vodama. Sa druge strane, povećana svest o štetnosti visokih koncentracija ovog polutanta u pijaćoj vodi, dovela je do strožijih standarda kada su ovi joni u pitanju. Zato se poslednje decenije vrše intenzivna ispitivanja novih metoda za uklanjanje fluoridnih jona iz otpadnih i pijaćih voda. U ovom radu je ispitana mogućnost upotrebe aluminijum alginatnih čestica, jeftinog i efikasnog adsorbenta, za uklanjanje fluoridnih jona. Detaljna karakterizacija primenjenog adsorbenta urađena je pre i nakon adsorpcije primenom FT-IR tehnike. Eksperimenti su izvedeni u šaržnom sistemu sa mešanjem, pri različitim polaznim koncentracijama adsorbenta i adsorbata. Dobijen rezultat od 11,40 mg F-/g Al-alginata ukazuje na visok kapacitet adsorbenta, a kinetički parametri pokazuju brzu kinetiku uklanjanja ispitivanog polutanta.sr
