share of resistance controls the rate of adsorption. The resistance of the transition
steps depends on several factors such as the type of adsorbent and adsorptive and
operating conditions (Amanullah et al. 2000; Plazinski and Rudzinski 2009).
Various factors affect the adsorbent properties, the most important of which is
shown in Fig. 16.6.

properties can be
controlled by tuning the
structural and surface
factors. The figure shows
the most important factors

properties
Fig. 16.5 Adsorption process takes place through some transition steps. These steps include external diffusion of adsorptive molecules within the fluid bulk to the outer surface of the adsorbent,
intraparticle diffusion or intra-pore diffusion, and the surface reaction
