Kinetics of sorption
is one of the important parameters in the sorption
process, since it helps in determining the contact time needed for optimum sorption
, which depends on the nature of the system used.
ESMs could readily exploit quantitative relationships between more widely measured soil physicochemical properties and phosphate sorption
, if such relationships were available.
Van der Waals forces and hydrogen bonding are responsible for the speedy sorption
process in the start that later on slow down due to sorbent swelling, complexes formation and particle structure breakage (Hance, 1967; Gevao et al., 2000).

kinetics was conducted at 24[degrees]C, in 100-mL amber glass container using the procedure described by Martins & Mermoud (1998), with SMX concentration of [10.sup.-4] mol [L.sup.-1].
Keeping in view importance of sorption
studies of pesticides, the present study focuses on adsorption desorption characteristics of benzimidazole based fungicide Benomyl on selected agricultural soils of Pakistan.
From this point of view, the magnetic sorbents based on clay minerals are of great scientific and practical interest, since they combine unique sorption
properties and low cost of clays with the possibility of their rapid separation from the suspension after the sorption
process is completed by means of the magnetic field.
thermodynamics experiments were conducted at the temperature ranging from 25[degrees]C (298 K) to 45[degrees]C (318 K), and the initial concentration of OTC ranged from 5.0 mg/L to 25.0 mg/L.
From the temperature dependence of the sorption
isotherms, the isosteric heat of sorption
Adsorption is a very complex water remediation process that depends on a wide variety of parameters, including (a) water properties, such as pH, redox potential, and ionic composition of water (other ions present in water can compete with As for sorption
sites); (b) As properties (particularly, the speciation or oxidation state); and (c) sorbent properties, such as the surface area, the size, the reactivity, and the number of sorption
active sites .
Thermodynamic of sorption
. The results of enthalpy of activation energy ([DELTA]H), Gibb's free energy ([DELTA]G) and entropy ([DELTA]S) were obtained from the plot of slope and intercept of enthalpy of activation energy for all above metal ions, and given in Table 2.
Because of the complexity of the cell structure and the range of effective channel sizes and surface areas, we use the term "sorption
" to refer to the combined process of solvent transport in wood.
