Abstract

Acetic acid is widely used as an industrial chemical due to its very good solvency and miscibility. It is also used as a reagent in the production of many industrial chemicals. The major use of acetic acid is in the manufacture of vinyl acetate monomer, narrowly followed by acetic anhydride and ester. The total worldwide production of acetic acid is expected to reach 15.5 Mt/a (million tons per year) by 2020. Waste Acetic acid with pH of 5 or lower is termed as a dangerous waste. There are many methods used for removal of acetic acid from aqueous solutions; however these are also energy and cost intensive. Adsorption is one of the alternate methods which can be used for the removal of acetic acid. Considering the economics, there is increasing research interest in using alternate low cost adsorbents. In this work, adsorption of acetic acid from aqueous solutions by using Rice husk has been explored. The adsorption of Acetic acid in continuous mode has been studied with two variables (adsorbent dosage, adsorbate dosage), keeping one constant at a time. Breakthrough curves were obtained. The results showed that the proposed adsorbent is very useful for removing Acetic acid from industrial wastewater.
