Abstract

In this study, the adsorption of acetic acid on the so-called "green" adsorbents
was studied. Waste materials, i.e. eggshells and coffee grounds were used as
adsorbents. In addition, activated carbon was used to compare the adsorption
efficiency with "green" adsorbents. The obtained results showed that the
equilibrium time of all studied adsorbents is achieved in 30 minutes. By
comparing the adsorption efficiency of acetic acid on the tested adsorbents, it
was shown that their use as cheap adsorbents under the tested conditions is
possible. The coffee grounds showed a relatively high adsorption efficiency,
very similar to the adsorption efficiency obtained when using the commercial
and most commonly used adsorbent, i.e. activated carbon.
