Randová, A. ; Bartovská, L. ; Hovorka, Š. ; Friess, K. ; Izák, Pavel
In this work the study of sorption characteristics of PDMS in ternary system benzene (1) + methanol or butanol (2) + ionic liquid (3) and corresponding binary subsystems at the temperature of 20°C is presented. The experimental data on total sorption were determined gravimetrically [3], the experimental data on preferential sorption were evaluated from the concentration change induced by an immersion of the membrane into the liquid mixture [3]. The volume changes of swollen membrane immersed in the studied liquid systems were determined from the dimensional changes of the membrane samples changes in X and Y axis dimensions were monitored directly in liquid by an optical method [1, 3] and membrane sheet thickness was measured by an Inductive Dial Indicator (Mahr, Germany).
