Thermodynamic parameters
were calculated to predict the theoretical behaviour of the
adsorption process. The isosteric heat of adsorption decreased
with an increase in surface loading. The adsorption capacity of the
adsorbent was compared with that of activated carbon (E-Merck,
India), showing that organoclay is very effective for the removal of
TCP. The adsorbent can be regenerated and reused by alkali
treatment. By using this adsorbent, TCP can be effectively removed
from real industrial waste-water.
