Abstract

Excess fluoride ion (F) in drinking water causes harmful effects such as dental and skeletal fluorosis. Hence, its concentration in drinking water must not exceed a certain range. This study investigated the removal of F from aqueous solutions with CuO nanoparticles using a range of experimental approaches, including pH, adsorbent dose, contact times, and initial F concentration. The equilibrium adsorption data were analyzed using the Langmuir and Freundlich adsorption models. The maximum uptake value of F was 3152 mg/g at pH 5 during 40 min with 0.005 g/L nanoparticles of CuO and an initial F concentration of 5 mg/L. The fluoride adsorption equilibrium over the adsorbent was well described by the Freundlich model. The findings of this study showed that CuO nanoparticles are quite effective for F removal from aqueous environments. Thermodynamic analyses showed that the adsorption of F onto CuO nanoparticles was endothermic and spontaneous. © 2016 The International Society for Fluoride Research Inc.
