INTRODUCTION Despite its range of applications, aluminum is one of the rare affluent elements which seemingly have no positive impacts on the living cells. At high quantity, it affects the blood circulation and nerve systems 1 . Aluminum would be absorbed more from food stuffs than water 2 . Studies have revealed that consumption of acidic food stuffs and liquids containing aluminum could result in considerable increment of aluminum absorbance 3 . Poly aluminum chloride (PAC) and aluminum sulfate are mineral coagulants which have been highly used in recent years for removal of color and turbidity in the water treatment industry 4-8 . Having been added to the water, a part of coagulants would be ORIENTAL JOURNAL OF CHEMISTRY www.orientjchem.org An International Open Free Access, Peer Reviewed Research Journal ISSN: 0970-020 X CODEN: OJCHEG 2014, Vol. 30, No. (3): Pg. 1365-1369 Removal of Aluminum from Water and Industrial Waste Water PARISA GHASHGHAIEE POUR 1 , MOHAMMAD ALI TAKASSI 2 * and TOUBA HAMOULE 2 1 Department of Chemistry, Science and Research Branch, Islamic Azad University, Khouzestan, Ahvaz, Iran. 2 Department of science, Petroleum University of Technology, Ahwaz, Iran. http://dx.doi.org/10.13005/ojc/300356 (Received: May 30, 2014; Accepted: July 08, 2014) ABSTRACT This study attempts to introduce a procedure to remove Aluminum ions from drinking water and industrial effluents by using active carbon with different grading as absorbent. Absorption of Aluminum ions were discussed in different conditions of Aluminum concentration, contact time, impact of electrolytes and pH on Aluminum ions absorbency. Both Freundlich and Langmuir isotherms used to investigate the adsorption. Thermodynamics relations governing process, such as specification of (ΔG°), (ΔS°) and the enthalpy of adsorption, were calculated, which showed that Aluminum absorption on active carbon is an endothermic and spontaneous process. Key words: active carbon, adsorption, industrial effluents. dissolved and remained in the final treated water. Aluminum is among elements existing in aluminum- based coagulants (e.g. PAC and Alum) that even its trivial amount in the water causes numerous health problems including Alzheimer and dialysis encephalopathy 9 . The maximum allowable aluminum extent in drinking water is set 0.2 Mg/L by the Environmental Protection Agency (EPA). Ideally, the aluminum extent in drinking water should be less than 0.05 milligram per liter and the maximum level allowed is 0.2 milligram per liter. Having access to safe drinking water is considered among the essential needs of any community. The population growth and development of cities, industries etc. have polluted the environment and supplying sources of drinking water in particular 10,11 . Preserving the quality
