ABSORPTION OF ORGANIC MATTER BY USING MODIFIED ACTIVATED CARBON BASED ON IRON METALS

Abstract

The content of this paper is to evaluate organic matter removal from aqueous solution by using activated carbons contained iron metals (MAC). The absorption method was conducted. The effect of the ratio (0-5%, w/w) of iron metals and activated carbons, pH (4-10), initial organic matter concentrations (250-1000mg/L), flow rates (10-30mL/min), the height of the adsorbent column (10 -30cm) on the adsorption system were studied. Sorption of organic matter on the activated carbons could be described by kinetic models: Thomas, Yoon-Nelson and Bohart-Adam. The results showed that the optimum condition was at the ratio of 3% and pH of 7. The optimum adsorption process (79.71%) reached at the initial organic material concentration of 500mg/L, the flow rate of 10mL/min and MAC fixed-bed height of 30cm. The results also approved that MAC can be used as a potential absorbent to treat organic matter.
