Batch adsorption isotherm studies were carried out using Type
C hair in all three oil types. Experiments were performed in
triplicate with samples withdrawn at intervals ranging from 5 to
80 min. The experimental data obtained were analysed using
Lagergren pseudo-first-order and second-order kinetic models
[29] and the Langmuir [30] and Freundlich [31] adsorption
isotherm models. The experiments were conducted with varying
weights of the adsorbents to determine the adsorption capacities.
The kinetics and adsorption isotherm were also investigated.
