Abstract
The present communication provides the eliminating of heavy metals from water resources using Ag-Mg/TiO2 nano particles. The Nanoparticles with a size of 15nm were synthesised using sol-gel technique .The doped oxide is subsequently used for the removal of Cr (VI) and Cu (II) from waste waters. Batch sorption studies were carried out to investigate the adsorption of the above trace metal ions for a concentration range of 0.1 mg/L to 10 mg/L. The maximum sorption capacity values were found to be 2.42 mg/g for Cr (VI) and 2.03mg/g for Cu (II) at a concentration of 0.1 ppm. The mechanism of adsorption was also investigated. Isothermal, kinetic and thermodynamic studies were also carried out to study the adsorption capacity . The value of the thermodynamic parameter ΔH° revealed the endothermic adsorption process and negative value of ΔG° shows the feasibility and spontaneity of material–anion interaction. In addition the method is considered to be simple and cost effective and shows excellent adsorption removal properties on heavy metals for industrial applications.
