Abstract

Abstract: The present study reports synthesis of layered double hydroxide (LDH) – poly(diallyldimethylammonium chloride) (PDDA) nanocomposites, their characterization and application for adsorptive removal of an azo-dye from water. LDH-PDDA nanocomposites with different PDDA concentrations were synthesized through a facile method. The physico-chemical characteristics of the nanocomposites were studied by TGA, XRD, FTIR, FESEM, HRTEM, zetasizer and surface area/porosity analyzer. The adsorption property of the LDH-PDDA nanocomposites was investigated for the removal of orange II dye from water. Adsorption kinetics, equilibrium and isotherm experiments were performed to study the adsorption characteristics of the LDH-PDDA nanocomposites. The dye adsorption capacity and the rate of adsorption of the nanocomposites were found to be influenced by the polymer content in the composite. The orange II adsorption capacity of the LDH-PDDA composite is approximately two times that of the pristine LDH.
