Adsorption is the surface phenomenon; it is widely application for the recovery/removal of various dyes, heavy metal cations and anions. The kinetics of these phenomena is of great significance to evaluate the performance of a given adsorbent and gain insight into the underlying mechanisms. Adsorption is one of the most widely applied techniques for environmental remediation. There are many types of models existing for catering different types chemical/physical conditions. There is huge amount of literature available concerning adsorption kinetics, and several mathematic models have been developed to describe adsorption reaction and diffusion processes. However, these models were frequently employed to fit the kinetic data in an unsuitable or improper manner. This is mainly because the boundary conditions of the associated models were, to a considerable extent, ignored for data modeling.
