Studying effects of ion exchange resin structure and functional groups on Re(VII) adsorption onto Purolite A170 and Dowex 21K
The effects of the functional groups and structures of two different resins, weak base/macroporous and strong base/gel type, Purolite A170 and Dowex 21K on the adsorption properties of Re(VII) ions were investigated experimentally and described by the isotherm, kinetic, and thermodynamic modeling. In this regard, four widely used adsorption isotherm models including Langmuir, Freundlich, Temkin...
متن کاملEsterification Reaction Kinetics Using Ion Exchange Resin Catalyst by Pseudo-Homogenous and Eley-Ridel Models
This work deals with kinetics and chemical equilibrium studies of esterification reaction of ethanol with acetic acid. The esterification reaction was catalyzed by an acidic ion exchange resin (Amberlyst-15) using a batch stirred tank reactor. The pseudo-homogenous and Eley-Rideal models were successfully fitted with experimental data. At first, Eley-Rideal model was examined for heterogeneous...
متن کاملThe agglutination of ion exchange resin particles coated with polysaccharide.
NH20H + DPN2H -* NH40H + DPN. If NH4OH is used as substrate and the pH maintained above neutrality, the reverse reaction can be demonstrated (figure 1). In the absence of substrate, extract, or coenzyme no decrease in transmission was noted. NH4C1 and (NH4)2S04 were inactive as substrates at pH 7.0. The enzyme is stable at 60 C for 5 minutes, but not at 65 C. No loss of activity was noted after...
متن کاملDynamic Drying of Benzene with Ion-exchange Resin
Various organic solutions are used in many industries such as the petrochemical industry. The presence of moisture in those solvents results in poor insulation, corrosion of apparatus and catalyst poisoning. Therefore, the moisture content of the solvents must be reduced to less than several ppm. Since ion exchange resins have an ability to adsorb selectively polar substances fromnonpolar solve...
متن کاملThe preparation of diphosphopyridine nucleotide with ion exchange resin.
The older methods for the preparation of diphosphopyridine nucleotide (DPN) were reviewed in 1942 by Schlenk (1). In 1947 Sumner et al. (2) outlined the need for a greatly simplified method for the preparation of this coenzyme. These authors described a procedure which did away with heavy metal fractionation. Recently, Clark et al. (3) made several modifications in the above method. The LePage ...
