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.
Activated carbon was modified with potassium permanganate. Adsorption capacity of chromium(VI) onto the modified activated carbon was investigated in a batch experiment system. The effect parameters studied include adsorption time, dosage of activated carbon, pH, and initial concentration of chromium(VI). Modification of potassium permanganate improve the adsorption efficiency of chromium(VI) on activated carbon by nearly 50%. The Langmuir and Freundlich isotherm were used to describe the adsorption equilibrium studies at different temperatures. Langmuir isotherm shows better fit than Freundlich isotherm in studied temperatures. The result shows that the modified activated carbon can be efficiently used for treatment of water containing chromium.
