present study deals with the adsorption of glycolic acid (ga) from aqueous solutions by using bagasse fly ash (bfa). bfa is a solid waste generated from bagasse fired boilers and can be used as an adsorbent. batch adsorption studies were carried out to evaluate the effect of various parameters like adsorbent dose, contact time, initial concentration and temperature on the removal of ga from aq...

almcm-41 was applied for adsorption of methylene blue (mb) and auramine (au) in single and binary component systems. in the single component systems, almcm-41 represents higher adsorption capacity for mb than au with the maximal adsorption capacity of 2.07×10−4 and 1.15×10−4 mol/g at 25 ˚c for mb and au, respectively. in the binary component system, mb and au exhibit competitive adsorption onto...

In preparation of chemical studies with superheavy elements around Z = 114, the adsorption behavior of these elements and their lighter homologs on different metals has been predicted based on (semi-)empirical models and extrapolations (see e.g. [1, 2]). Adsorption studies with SHE homologs were performed on various metals, especially metals of group 10 and 11 (see e.g. [3]). The experimental r...

In this paper, the adsorption of cerium on modified Mesoporous aluminosilicate (with Si/Al mole ratio of 10) was studied. The effects of pH, contact time, initial concentration of cerium on adsorption of cerium were investigated. The adsorption capacity was high in the pH range of 4-8 and decreases with decreasing of the pH value. The Langmuir and Freundlich isotherms were applied to represent ...

Density functional theory (DFT) calculations were performed to investigate adsorptions of vitamin C (Vit) on the surface a fullerene structure (Ful) in gaseous and water–solvated systems. Two models of Vit including OVit and MVit were created based on the original structure of Vit for OVit and methylation of all hydroxyl groups for MVit. All singular and hybrid structures were optimized and the...

Since its invention in 1986 by Binnig, Quate, and Gerber, the atomic force microscope (AFM) has proven to be an extremely useful tool for examining the interactions of proteins with surfaces. Fibrinogen in particular has been used as a model protein to demonstrate new methodologies for studying protein behavior with AFM due to its unique size, shape, and function. Indeed, fibrinogen's central r...
