Sorption of organic vapors in Teflon AF 2400 and LDPE membranes
Original language description
This work deals with the sorption of organic vapors (methanol, ethanol, chloroform and acetone) in polymer membranes Teflon AF 2400 and low-density polyethylene Bralen FB2-30 at the temperature of 25°C. The sorption apparatus with Mc Bain spiral quartz balance enables to follow the sorption kinetics. From this data the appropriate diffusion coefficients D of organic vapors are calculated. Teflon AF 2400 (2,2-bistrifluoromethyl-4,5-difluoro-1,3-dioxole/tetrafluoroethylene copolymer) is an ultra-high freevolume polymer, which exhibits unique sorption properties. Sorption isotherms of the both polymers were determined. The isotherms of chloroform are plotted to the minor axis due to higher sorption amounts in both polymers.
