Waste Water Remediation using an Adsorbent Material

Function of lemon peels as a natural and affordable sorbent to remove Ni (II) ions from simulated aqueous solution were examined by using batch adsorption experiment. A cluster of parameters which influence on adsorption process were studied including pH, quantity of sorbent and the time of agitation which required to reach to equilibrium in order to meet the optimum circumstances for Ni (II) ions removal. Isotherm study was conducted to describe the sorption process. The maximum elimination percentage was 86.5 at pH 6.5, 1.5 g of lemon peels and 1-hour contact time. Freundlich isotherm was best to describe the results.
