The exploitation of Delonix regia fruit pod (DRFP) as the low-cost biodsorbents is verified as an alternative for current pricey techniques for elimination of nickel ions from aqueous solutions. Batch adsorption studies is conducted to examine the effects of physico-chemical key parameters such as the initial metal ion concentration, pH, agitation time, stirring rate and adsorbent dosage on the adsorption from Delonix regia fruit pod (DRFP). The % adsorption, Langmuir constants, Freundlich constant for [Ni(II)] were determined for the adsorption system as a function of sorbate concentration. Equilibrium data were analyzed using the Langmuir and Freundlich isotherms whereas the adsorption kinetics data is also evaluated.
