Swelling

Hydrophilic polymers with pendant functional groups form polymeric supports for various technological applications such as ion exchange, reagents, anchoring agents and catalysts. In the present study, 2- acrylamido-2methyl propane-1-sulphonic acid (AAmPSA) was polymerized by chemical initiation meth

Application of the liquid emulsion membrane (LEM) technology to the industrial scale is hindered by the challenges imposed by stability of the emulsion during the transfer of the solute (pertraction). One of the important factors which leads to the instability is swelling. Emulsion undergoes swellin

Sorption, diffusion and permeation of halogenated liquids such as chloroform, dichloromethane, carbon tetrachloride, 1,2-dichloroethane, 1,1,2,2-tetrachloroethane, trichloroethylene and tetrachloroethylene into commercial fluoroelastomer (FC-2177 D) were studied at 30, 40 and 50EC using the sorption

Chloride-nitrate equilibrium was studied using the Neosepta ACS anion-exchange membrane. Ion-exchange isotherm and selectivity coefficient were performed on the basis of the Donnan equilibrium and Helfferich’s equilibrium relationship. Fixed ionic group concentration and water activity coefficients
