Sažetak
Heightened fluoride concentration in drinking water can cause health problems such as immunological defects, dental and skeletal fluorosis, reproduction problems and induces birth. Several techniques have been worldwide used for fluoride removal from water: coagulation and precipitation, electrochemical treatments, ion-exchange, membrane filtration and adsorption. Among all above mentioned, adsorption technique is considered to be cheapest and efficient enough method for fluoride removal. In this study the batch tests were used to define efficiency of fluoride removal from aqueous solution using nutshell-based activated carbon, i.e. the effects of initial fluoride concentration (2-100 mg/l) and solution temperature (25-45°C) were examined. Up to 46% fluoride was removed. The obtained adsorption data were analyzed using the Langmuir and Freundlich isotherm models showing that fluoride adsorption onto nutshell-based activated carbon fits the Freundlich model well.
