Thermodynamic and Kinetic Study of the Adsorption of Pb (II) from Aqueous Solution Using Bentonite and Activated Carbon

Al-Khawarizmi Engineering Journal, 2013
The adsorption of Pb(II) ions onto bentonite and activated carbon was investigated. The effects of pH, initial adsorbent dosage, contact time and temperature were studied in batch experiments. The maximum adsorption capacities for bentonite and activated

Recovery of phenylethyl alcohol from aqueous solution by batch adsorption

Open Chemistry
Adsorption of phenylethyl alcohol (PEA) from aqueous solution onto Macronet MN202 was carried out by batch experiments. The effects of initial PEA concentration (250–6,000 mg L−1), adsorbent amount (0.025–1 g), and temperature (25–40°C) on the adsorption

Diffusion Influenced Adsorption Kinetics

The Journal of Physical Chemistry B, 2015
When the kinetics of adsorption is influenced by the diffusive flow of solutes, the solute concentration at the surface is influenced by the surface coverage of solutes, which is given by the Langmuir-Hinshelwood adsorption equation. The diffusion equation with the boundary condition given by the Langmuir-Hinshelwood adsorption equation leads to the ...

Kinetics of polyelectrolyte adsorption

Journal of Physics: Condensed Matter, 1997
The kinetics of polyelectrolyte adsorption has been investigated theoretically. In analogy with Kramers' rate theory for chemical reactions we present a model which is based on the assumption that a polyelectrolyte encounters a barrier in its motion towards an adsorbing surface. The height of the barrier, which is of electrostatic origin, is calculated

Protein ion‐exchange adsorption kinetics

AIChE Journal, 2001
AbstractThe kinetics of the adsorption of the protein BSA on the ion exchanger Q‐Sepharose FF were measured for several values of the pH and ionic strength, using several techniques. The measurements were best described with a model incorporating both surface and pore diffusion and with the chemical potential gradient as the driving force for diffusion.

Kinetics of Random Sequential Adsorption

Physical Review Letters, 1989
We present the first kinetic analysis specifically applicable to the random sequential adsorption (RSA) process in the intermediate coverage range. Our method is applied to hard disks adsorbing on a flat, uniform surface. Exact analytic expressions are derived for the first three coefficients of a power series for the rate of adsorption as a function ...
