Sažetak
The aim of this study was to determine the adsorption characteristics of three different adsorbents for removal of As(V) from water. Adsorption characteristics of two arsenic removal media: Bayoxide® E33 (granular ferric oxide) and Titansorb® (granular titanium oxide) as well as adsorption characteristics of the suspension of precipitated ferrihydrite were determined. Obtained results were fitted to Freundlich and Langmuir adsorption isotherm equations. The value of separation factor (RL) for all three used adsorbents ranged from 0.04 to 0.61 indicating effective adsorption. Highest capacity for As(V) adsorption was observed for precipitated ferrihydrite and lowest for Titansorb. Bayoxide and precipitated ferrihydrite had higher capacities for As(V) adsorption in demineralized water compared to tap water while Titansorb, had higher capacity for As(V) adsorption in tap water.
