Graphene-derived permeable membrane with ion selectivity permits outgoing and incoming of selective ions (e.g. positively or negatively charged in a system). They consist of ion channels that facilitate the efficient separation and transport of different ions. As such, these membranes are employed to produce required ions via electrolysis of salt solution during a process.
The technology relates to the use of functionalized graphene oxide (GO) based membranes so as to separate ions from the feed stream for the purpose of kidney dialysis, nanofiltration or ion exchange. The membrane is a graphene-based membrane with an electrical charge, in which layers of graphene-based material are stacked together, with one or more nano-channels between neighboring layers.
Pharmaceutical, chemical & fuel separation applications with the following processes:
The ion-selective permeable membrane market is driven by the rise in awareness for wastewater treatment and rapid growth in installations of energy-related systems in different regions worldwide. However, the high cost of these membranes may restrain the market growth during the forecast period. Moreover, the increase in demand in emerging economies is expected to provide potential growth opportunities for the growth.
