Adsorption kinetics helps to predict the rate at which the
adsorption takes place and aids in selecting the optimum operating conditions in designing and optimising full-scale applications. In
this study, the adsorption kinetics of Type C hair for diesel fuel and
vegetable oil were investigated by using the pseudo-first order and
pseudo-second order adsorption models. Pseudo first order and
pseudo second order were proposed by Lagergren [29] and can be
expressed, respectively in linear form as:
