Nettet14. apr. 2024 · When the volume fraction of gelatin is 2.4%, the mechanical properties of foam are the best. The stress of the foam is 55.746 kPa at 60% deformation, and the adsorption capacity reaches 57.061 g/g. The results can serve as a reference for the preparation of highly stable cellulose-based solid foams with excellent adsorption … Nettet18. okt. 2006 · It is found that linear adsorption exhibits low exothermic heats and practically no adsorptive competition. The solute−solid configuration and the adsorptive force consistent with these effects were hypothesized. For nonpolar solutes, the adsorption occurs presumably by London (dispersion) forces onto a water film above …
Nettet26. jan. 2024 · Adsorption rate constants do not depend on the partial coverage of adsorbate: That is, all adsorption sites are identical and mutually independent; Adsorption is a second-order process whose rate is linear in the adsorbate concentration in the bulk phase adjacent to the surface, as well as the proportion of vacant sites Nettet14. apr. 2024 · To determine the competitive adsorption characteristics and influencing factors of chlorinated and aromatic hydrocarbons on the aquifer medium, toluene, benzene, 1,2−dichloropropane, and 1,2,3−trichloropropane (TCP) were selected as typical pollutants for adsorption tests. The results showed that the adsorption process of …
NettetIn order to model transport of contaminants through the subsurface a linear adsorption isotherm is usually used because of its simplicity (Sharma and Reddy, 2004). With increasing contaminant concentration an initial linear increase in sorption is followed by a slowing and nonlinear rate of sorption increase as the ... Nettet10. jul. 1999 · The problem of multiple-site adsorption chromatography is connected with a great number of questions of both chromatographic nature (e.g., the effects of surface heterogeneity on the column efficiency and on the peak shape parameters) and physical chemical relevance (e.g., the study of residence time in one sorption step on …
NettetRepresentation of the range of isotherm linearity for a given separation system. We have already seen that the Langmuir isotherm becomes linear at small sample concentrations (Section 3-2B). It may be shown similarly that any real adsorption system (i.e., where the energies of adsorption on the strongest sites are finite) becomes linear at ...
