Sorption of Organic Vapors in Polymer Membranes
Original language description
Sorption of organic vapors (benzene, toluene, cyclohexane, hexane and heptane) in polymer membranes LDPE (low density polyethylene) and PEBA (polyether block amide) at 25 °C was studied. The glass sorption apparatus with Mc Bain spiral quartz balance enabled to follow the sorption kinetics of organic vapors. The appropriate diffusion coefficients D of organic vapors were calculated from experimental data by 3 different methods and polymer-solvent interaction parameters were calculated by Flory-Huggins equation. Both polymer membranes, which has been used in this work, are commercial products. Low density PE membrane BRALEN FB2-30 (thickness 50 mm) is produced by Slovnaft, a.s., Slovakia and polyether-block-amide membrane PEBA 4033-PE (thickness 120 mm)is produced by GKSS, Germany. PEBA membrane contains supporting polyester lattice which does not participate in vapors sorption.
