This contemporary study reveals the potential of modified Phoenix Dactylifera L. seeds as a biosorbent to adsorb Ni (II) ions present in simulated wastewater. The effect of initial pH and contact time on the uptake of Ni (II) ions were studied. Increase in pH from 3 to 5 increased the removal efficiency from 7.68 to 24.8 %. Pseudo 2^ndorder(PSO)model was found most suitable in kinetic studies. Equilibrium was reached within first 20 minutes. Chemisorption was proved to be the rate limiting step(RLS) in biosorption of Ni (II) ions on modified Phoenix Dactylifera L. seeds.
