Abstract
The development of rapid and reliable processes for the synthesis of nanomaterials is of great importance in the field of nanotechnology. In this paper, the modified forms of chitosan beads such as carboxylated cross-linked chitosan beads (CCB), Grafted cross-linked chitosan beads (GCB) and Protonated cross-linked chitosan beads (PCB) were prepared synthetically from chitosan beads by chemical method. The synthesis of modified chitosan beads/TiO2 nanocomposites was carried out by using LPD (Liquid Phase Deposition) technology in aqueous medium. The method was performed by mixing the modified chitosan beads with TiO2 in the presence of PVA has been used as the capping agent. The synthesized nanocomposites were characterized by XRD, SEM with EDAX and UV-vis absorption spectroscopy. The present study was conducted to evaluate the feasibility of modified chitosan beads/TiO2 nanocomposites for fluoride adsorption from aqueous solution. The residual adsorbents were also characterized by using XRD and SEM with EDAX analysis. A batch adsorption study was performed with function of contact time.
