Abstract

The environmental pollution of harmful toxic metals is one of the important issues in the world today. NICKEL is one of the toxic heavy metals which if enters into the human body in high concentrations, it will cause skin allergy, heart disease and various cancers. Therefore, this is apressing necessary to remove NICKEL from industrial wastewater. The purpose of this study is firstly to remove NICKEL from aqueous solutions with synthesized ACTIVATED CARBON from carrot remains and secondly to investigate the effect of variations of the adsorbent PARTICLE SIZEs on the equilibrium time and the removal efficiency. To this end, adsorption of Ni (II) ions on the adsorbent was studied in a batch process. Firstly, the ACTIVATED CARBON was prepared from carrot remains with PARTICLE SIZEs between 37 and 300 micrometers. The results showed that the maximum absorption efficiency occurs (100%) at pH of 6. Moreover, it was shown that with decreasing the adsorbent size from 300 to 37 mm, the equilibrium time will decreases from 130 to 20 min. Experimental data was best fitted onto pseudo-second order model. Langmuir and Freundlich isotherms equation were used to fit the ADSORPTION ISOTHERMs. It is evident from this study that ACTIVATED CARBON is a suitable material for the uptake of Ni (II) from aqueous solutions.
