A variety of methodologies and routes have been reported for the adsorption of heavy metal ions like Cd, Hg, Cu, Zn, Ni, etc. aiming at increased potentials in waste water treatment. In this paper an elegant approach towards removal of heavy metal ions is reported using Silver-Delonix regia nanocomposite. FTIR results indicated the presence of a number of active sites in the composite comparable to Activated Charcoal. uv-vis spectra showed the formation of nano silver for the nanocomposite. Nanosilver-Delonix regia composite could well be used as a viable alternative in future for improving the adsorption potency. The nickel ions adsorbed on the nanocomposite was subjected to both Freundlich and Langmuir isotherms.
