Pervaporation Membrane Exhibiting High Biocompatibility Based on PDMS/PEO Alternately Grafted Aromatic Polyamide

Pervaporation of aromatic Cg-isomers

A pervaporation process was applied to the separation of different mixtures of aromatic Csisomers using a dense homogeneous polyethylene membrane. The influence of feed temperature and downstream pressure on the flux of pure components was investigated. For mixtures, the effect of feed composition on permeation rates and separation characteristics was determined. Molar fluxes and separation fac...

PVC-Based Cerium Phosphate Membrane Exhibiting Selectivity for Molybdate Anions

A PVC-based membrane containing cerium phosphate was developed. Unlike the cerium phosphate itself that acts as a cation exchanger, the membrane exhibited anion-exchange properties. Therefore, the utility of this compound as a sensory element for detection of molybdate ions was pursued. The response of molybdate selective electrode based on this membrane was perfectly linear in the concentr...

Pervaporation: Membrane Separations

G-100 is used for higher molecular mass proteins. The solutions of proteins are prepared in guanidine hydrochloride (10 mg mL ), and cytochromec (10 mg mL ) is used as an internal standard. Descending chromatography is carried out at room temperature under an inclination angle of 253 to the horizontal. After 3 h of development the quotient Rs protein/Rs cytochrome c is calculated for each prote...
