3b, d, and f) indicates that all these membranes' separation layers are all tightly and properly covered on the top of the PVDF supporting layer, which is important for pervaporation
2]; and t is the collection time for the pervaporation
The influence of support layer on mass transport of homologous series of alcohols and esters through composite pervaporation
is a process in which a liquid stream containing two or more components comes in contact with one side of a nonporous polymeric membrane while a vacuum or gas purge is applied to the other side.
It was the work by Binning and co-workers |4,5,6~ from 1958-1961 that established the principles and highlighted the potential of pervaporation
Cascon, who holds a PhD in environmental engineering and biotechnology from Myongji University (Yongin Campus), South Korea, specializes in alcoholic biofuel separation using ionic liquid-based membranes in the pervaporation
Among the membrane separation techniques, pervaporation
has been successfully applied for the separation of such organic mixtures owing to its relative simplicity and energy saving aspects [1-3].
Other topics include pervaporation
, electrophoretic and eletroosmotic treatments, ion exchange, air tabling, particle shape characterization by image analysis, and Brunauer-Emmett-Teller surface area measurements.
Shieh and Huang  have reported the preparation and characterization of chitosan/N- methylol nylon 6 blends in the form of membranes for the separation of ethanol-water mixtures by pervaporation
Li, et al (2001) attempted to recover 1,3-propanediol by pervaporation
through a X-type zeolite membrane from a model 1,3-propanediol/glycerol/water solution and broth solutions containing glucose.
The first section of the book discusses recent advances in techniques, including supercritical fluid extraction, process chromatography, and membrane technologies, as well as emerging techniques such as pervaporation
and pressurized liquid extraction.
