Description :
This paper provides application of non-conventional adsorbents for removal
chlorophenol from wastewater. Adsorption equilibrium and kinetics of 2, 6-
Dichlorophenol (2, 6-DCP) one of the chlorophenols (CPs) onto three different types of
polymeric adsorbents ( XAD-4 , XAD-1180 and XAD7HP ) were studied in aqueous
solution in a batch system. Langmuir isotherm models were applied to experimental
equilibrium data of 2, 6-DCP adsorption. Equilibrium data fitted very well to the
Langmuir equilibrium models of 2, 6-DCP. Adsorption is very rapid in the first hour of
contact where 50 - 60 % of the adsorbate is removed in the first 40 minutes which is
then followed by a slow approach to equilibrium. The order of adsorption of 2, 6-DCP on
different adsorbents used in the study is found to be in following order;
XAD-4 > XAD-1180 > XAD7HP
