Selectivity as a function of membrane thickness: gas separation and pervaporation [PDF]
, 1994 In this article, the pervaporation selectivity as a function of the membrane thickness is studied for the dehydration of acetic acid. From this study, it appeared that the selectivity of polysulfone (PSF), poly(vinyl chloride) (PVC), and ...

Water clustering in polychloroprene [PDF]
, 2014 Water sorption has been studied gravimetrically for polychloroprene rubber samples, first at a fixed hygrometric ratio (98% HR) and several temperatures (25, 40, 60 and 80 °C) for samples of 1.8 and 3.8 mm thickness (Constant Temperature and Hygrometry ...

Effect of Water Sorption and Solubility on Two Soft Denture Lining Materials Stored in Three Different Mediums [PDF]
International Journal of Prosthodontics and Restorative Dentistry, 2023 Purpose: To evaluate and compare the effect on water sorption and solubility of acrylic-based and silicone-based soft denture lining materials stored over a period of 7, 14, and 28 days in three different storage mediums [distilled water (AW), artificial

CEC‐normalized clay‐water sorption isotherm [PDF]
Water Resources Research, 2011 A normalized clay‐water isotherm model based on BET theory and describing the sorption and desorption of the bound water in clays, sand‐clay mixtures, and shales is presented. Clay‐water sorption isotherms (sorption and desorption) of clayey materials are normalized by their cation exchange capacity (CEC) accounting for a correction factor depending on

Methods of using carbon nanotubes as filter media to remove aqueous heavy metals [PDF]
, 2012 Although carbon nanotubes (CNTs) are well known to have a strong affinity to various heavy metals in aqueous solution, little research has been dedicated to exploit their use in fixed-bed water treatment systems (e.g., trickling filters).

'GAB' generalised equation as a basis for sorption spectral analysis
Czech Journal of Food Sciences, 2010 The transformed sorption isotherm (represented by the ratio of water activity and moisture content (d.b.) versus water activity) was approximated by polynomials of 2nd-6th order.
