Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The sorption of chromium (VI), onto agricultural waste biomass carya shell (CS) over a wide range of reaction conditions was studied from aqueous solution. These conditions including the effect of solution pH, initial concentration, contact time on sorption efficiency. The chromium (VI) adsorption was favored with maximum adsorption at pH 1.0. The removal efficiency of chromium (VI) onto CS was decreased with increasing initial concentration. Biosorption equilibrium time was observed in 30min. The equilibrium adsorption data were fitted to Langmuir adsorption isotherm model and the model parameters were evaluated. The results showed that CS could be employed as a low-cost alternative adsorbent for the removal of chromium (VI) from aqueous solution.
