Investigation of growth kinetics of self-assembling monolayers by means of contact angle, optical ellipsometry, angle-resolved XPS and IR spectroscopy.
… dilute solutions has been monitored and Langmuir isotherm adsorption curves were fitted to experimental data. A saturated film is formed within approximately 5h after immersion in solutions of concentrations ranging from 0.0005mM to 0.01mM. We found, that the final density of monolayer depends on …

Rational Design of Supported Metal Catalysts for Carbonyl Reduction During Biomass Upgrading
… and rate controlling scenarios. Both of Langmuir isotherm adsorption and Temkin isotherm adsorption (lateral interaction) are counted respectively for the comparison of ketone hydrogenation over Pt and Ru catalysts. In the solvent system, various solvents (alkane, water, ether and alcohol) are …

Organic-inorganic hybrid materials for arsenic adsorption : surface complexation and intraparticle diffusion
… AT AUTHOR'S REQUEST.] Arsenic removal through adsorption is one of the most widely applied techniques for arsenic removal from drinking water. Among the numerous arsenic adsorbents that have been developed, organic-inorganic hybrid materials are promising candidates due to the merits of their …

Treatment of natural rubber wastewater using oil palm empty fruit bunch, kaolin and zeolite as composite adsorbent
… natural rubber wastewater. Batch and fixedbed adsorption techniques were used in this study. The combination ratio of zeolite, EFB and kaolin as a composite was optimised using D-optimal mixture design (DMD) while the characterization of composite adsorbents was done using Fourier Transform …

Development of a Design-Based Computational Model of Bioretention Systems
… to determine characteristics of blends. Isotherm experiments to examine P adsorption were also conducted to provide supplementary data for evaluation of bioretention media blends. The results show that the blend with water treatment residuals (WTR) removed >90% P from influent, and its …

Synthesis and potential application of Fe3+/Mn2+ bimetal and hexadecyltrimethylammonium bromide (HDTMA-Br) modified clayey soils for arsenic removal in groundwater
… found to be optimum at pH between 6 and 8. The adsorption isotherm data for As(III) and As(V) removal by both clays fitted better to Freundlich isotherm. Adsorption of both species of arsenic onto the clay mineral occurred via electrostatic attraction and ion exchange mechanisms. Both clay soils …

Adsorbents as mitigators in the Transport System of Nitrogen in Soil
We will be investigating based on review the adsorption properties of Bentonite, Biochar and zeolite as possible soil absorbents. The three have the most extensive scientific findings to back them up. We will concentrate on the adsorption behaviors in this thesis by employing Freundlich and …
