Comparative analysis of the effect ion-exchanger content in heterogeneous sulfonated ion-exchange membranes Ralex CM Pes produced by MEGA a.s. (Czech Republic) on their microstructure, current-voltage characteristics and intensity electroconvective instability was carried out. Using SEM method, it has been found that with an increase resin from 45 to 70 wt%, fraction surface swollen increases 1.8 times, distance between them is halved. At cross-section membranes, growth regions 46%. An...
A comparative analysis of the effect manufacturing technology heterogeneousion-exchange membranes Ralex CM Pes manufactured by MEGA a.s. (Czech Republic) on structural properties their surface and cross section SEM was carried out. The membrane is a composite sulfonated ion-exchanger with inert binder polyethylene reinforcing polyester fiber. In manufacture influence two factors investigated. First, time ion-exchange grain millingvaried at constant resin/polyethylene ratio. Second, ratio...
For the first time, based on joint application of fine-porous and cell models, a theoretical analysis changing transport structural characteristics heterogeneous polymeric ion-exchange membranes (IEMs) MK-40, MA-40, MA-41 after exposure to elevated temperatures in water aggressive media (H2SO4 NaOH solutions), as well long-term processing electrodialyzers various types, was carried out. The studied are composites polymers with polyethylene nylon reinforcing mesh. external influences provoke...
A simple non-steady state mathematical model is proposed for the process of purification an amino acid solution from mineral salts by method neutralization dialysis (ND), carried out in a circulating hydrodynamic mode. The takes into account characteristics membranes (thickness, exchange capacity and electric conductivity) (concentration components nature) as well flow rate dialyzer compartments. In contrast to known models, new considers local change ion concentration adjacent diffusion...
