Simultaneous adsorption of Cr(VI) and phenol by biochar-based iron oxide composites in water: Performance, kinetics and mechanism.

Journal of Hazardous Materials, 2021
The pollution of heavy metals and organic compounds has received increased attention in recent years. In the current study, a novel biochar-based iron oxide composite (FeYBC) was successfully synthesized using pomelo peel and ferric chloride solution ...

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.

Insight into the adsorption kinetics models for the removal of contaminants from aqueous solutions

, 2017
The past decade has seen a boom in environmental adsorption studies on the adsorptive removal of pollutants from the aqueous phase. A large majority of works treat kinetic modeling as a mere routine to describe the macroscopic trend of adsorptive uptake ...

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 ...

Magnetic COFs for the adsorptive removal of diclofenac and sulfamethazine from aqueous solution: Adsorption kinetics, isotherms study and DFT calculation.

Journal of Hazardous Materials, 2019
Covalent organic frameworks (COFs) are emerging and promising adsorbents for the adsorptive removal of many types of pollutants. However, most COFs fabricated by various methods are in the form of microcrystalline powders, making them difficult in ...
