µm and thermal neutron absorption.

Adsorption is a surface phenomenon, while absorption involves the whole volume of the material, although adsorption does often precede absorption. The term sorption encompasses both processes, while desorption is the reverse of it.

Adsorption involves the movement of contaminants from solution to the soil particles. Generally, soils are negatively charged but it would depend on the pH of the soil (Acar et al., 1993). The net charge in soil will be zero for a particular value of pH and that is called the point of zero charge (PZC). 2020-12-30 Adsorption technology has been widely applied in water and wastewater treatment, due to its low cost and high efficiency. The adsorption kinetic models have been used to evaluate the performance of the adsorbent and to investigate the adsorption mass transfer mechanisms. Adsorption process is usually studied through graphs know as adsorption isotherm.

Usually it is reversible (the reverse process is called desorption); then it is responsible not only for a subtraction of substances but also for release. Adsorption refers to the collecting of molecules by the external surface or internal surface (walls of capillaries or crevices) of solids or by the surface of liquids. Absorption, with which it is often confused, refers to processes in which a substance penetrates into the actual interior of crystals, of blocks of amorphous solids, or of liquids.
