4DescriptionAbstract Fire clay-TiO2 nanocomposite (NC) and fire clay (FC) was tested as adsorbents for the adsorption of Ni(II) from aqueous solutions. Batch adsorption experiments have been conducted under various operating parameters like initial metal ion concentration, contact time, adsorbent dose, pH and temperature. The equilibrium adsorption data on both clay and nanocomposite fitted well to Langmuir, Freundlich, D-R models and fairly to the Temkin model. The kinetic studies indicated that the adsorption followed pseudo second order, chemisorptive Elkovich and Intraparticle diffusion models. The thermodynamic parameters Δ Go, Δ Ho and Δ So evaluated showed that the adsorptions on both clay and nanocomposite to be exothermic and spontaneous in nature. Ni(II) removal was better with nanocomposite than with clay.
