Adsorption Characteristics of Bixin on Acid- and Alkali-Treated Kaolinite in Aprotic Solvents

Bioinorganic Chemistry and Applications, 2018
The adsorption of bixin in aprotic solvents onto acid- and alkali-treated kaolinite was investigated. Kaolinite was treated three times, for 6 h each, with 8 M HCl or 5 M KOH. The adsorbents were characterized by XRD, FT-IR, EDS, and BET-N2.

Kinetics of Particles Adsorption Processes Driven by Diffusion

, 1997
The kinetics of the deposition of colloidal particles onto a solid surface is analytically studied. We take into account both the diffusion of particles from the bulk as well as the geometrical aspects of the layer of adsorbed particles.

Heterogeneous Catalysis on a Disordered Surface

, 1995
We introduce a simple model of heterogeneous catalysis on a disordered surface which consists of two types of randomly distributed sites with different adsorption rates.

Adsorption of Lead Ions by Linde type F(K) Zeolite

MATEC Web of Conferences, 2016
The Test was to examine the adsorption property of Pb(II) irons by Linde type F (K) zeolite. The zeolite was synthesized by fly ash. The adsorbent dosage, pH, reaction temperature and reaction time were investigated.
