| Popis: | Fluoride 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. |
