摘要：

A novel adsorbent made of freshly obtained calcium oxide nanoparticles and ferric hydroxide dispersed in chitosan matrix (CHI-FCA) was prepared. Batch adsorption study was performed to analyze the effect of initial concentration, contact time, pH, and adsorbent dose on fluoride sorption on CHI-FCA. It was observed that maximum fluoride adsorption was achieved at pH 7.10 at an optimum equilibrium contact time of 180 min with an adsorbent dose of 8 g/L. Moreover, a synergistic effect was observed for fluoride remediation from aqueous medium. FTIR, XRD, DLS, TGA, DTA, and ESEM with EDX analysis were performed for the investigation reported here.
