This study involves the applicability of clam shell particles as an adsorbent for the removal of nickel from the water. Adsorption is a promising technology for the removal of heavy metals which have hazardous effects on the aquatic system and also on human beings. The aim of this work is to use clam seashells in the powder form for the removal of nickel. The Clam shell particles selected for the experiment has shown good adsorption capacities in the adsorption of Nickel. The mechanism of interaction between clam shell particles with Ni2+ was investigated using UV-Visible Spectrophotometer. Batch adsorption experiments were carried out to optimize the influencing parameters such as contact time, adsorbent dosage, pH, concentration and speed. The removal efficiency of nickel was found to be 90 % with a dosage of 0.50 g at a pH 6 for a contact time of 10 minutes with concentration of 50 mg/l at 150 rpm. Carbonaceous nanoparticles prepared through the Top-Down approach method were used to remove metal inorganic nickel ions in solution, by the adsorption of nickel ions. Nickel removal has been possible by using nano sized carbonaceous nanoparticle. The absorptivity of the flocs determined by the UV-Spectrophotometer shows that the process is efficient when dealing with aqueous nickel solution.
