Assessment of sorbent/water ratio effect on adsorption using dimensional analysis and batch experiments
No full textMany factors affect adsorption phenomena in solid–liquid systems. One of the most important factors is the sorbent/
water (S/W) ratio in the system. However, the effect of varying S/W ratios on the adsorption is still unclear. In this
study, batch experiments were examined to observe the adsorption of four contaminants (copper, cadmium, Butachlor,
and Deltamethrin) in six soils with texture ranging from silty clay to loamy sand and with different S/W ratios. Dimensional
analysis was used to assess the relationship between adsorption phenomena and S/W ratio. We have assumed
that the total amount of sorbate sorbed in soil is a function of the equilibrium concentration, the volume of sorbate
solution, and the sorbent amount in the system. A power function (Freundlich-like) model was obtained from the
dimensional analysis. It can describe precisely the adsorption phenomena of different sorbents and sorbates in the
moisture regime of paddy soils. Therefore, proper adsorption parameters can be obtained by this power function model
regardless of the solids effect, which can then be utilized to describe the fate of solute in soil using solute transport
models. 2002 Elsevier Science Ltd. All rights reserved
