PDMS

Pervaporation is a membrane technology utilizing a dense non-porous homogeneous polymeric film as a selective separation barrier. In recent years, pervaporation using dense membranes has emerged as a promising remediation method for trace organic removal from dilute aqueous solutions. The mathematic

The time-lag method can be easily used to characterize transport polymer features for permanent gases whereas with volatile organic vapors (VOCs) this routine procedure does not give valuable results, in particular in case of diffusion varying with activity, swelling of the polymer or small time-lag
