Isotherms; Kinetic Study of Adsorption of Acetic Acid on Marl Calcareous in Aqueous

Yassine Morad, Mustapha Hilali, Lahcen Bazzi

Abstract: The main applications of adsorption methods are among other surface treatment; water use for sewage and compensate for the consumption of fresh water; and soil remediation; where the activated carbon adsorption underpins most used; but with the advent of competition in the market and the downward trend in prices; several media were used because of their natural abundance; their low cost; etc. The research focused on the adsorption of acetic acid on marl calcareous. Studies in batch method were used to determine the contact time (0; 5 hour for a removal efficiency of 75 % at a concentration of 0; 2 mol/l substrate). However; this contact time may vary under the influence of parameters such as: temperature; concentration of adsorbate in solution; time; mass of adsorbent and pH revealed a significant improvement in the capacity and the rate of adsorption of acetic acid on the support. In addition; the adsorption of this compound is well described by kinetic models of Langmuir and Freundlich.

Keywords: organic molecule, acetic acid, temperature, pH, kinetic model, and marl calcareous
