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.
