casting of nano-graphene oxide with brominated poly(2,6-dipheyle-p-phenylene oxide) for optimization of co2 selectivity separation from mixture of gases by permeation membrane

In the recent decades, and especially after industrial revolution ,widely using of fuel fossils caused be increasing of greenhouse gases such as co2. increase of corporations , cars , improvement of industries and technologies are some reasons for worrisome in field of pollutions of air , water ,soil and other environmental problems .thus, produce of material for separation1 of co2 from mixture of gases and adsorption then desorption and analysis of them is very important. optimization of brominated poly (2,6-diphenyle –p–phenylene oxide)2 by casting3 with various percentage of nano-graphene oxide4 and preparation of permeations5 for compare and obtain the best percent of nano-graphene oxide for mixing with constant amount of brominated poly (2,6-diphenyle – p – phenylene oxide) caused be increasing of selectivity6 for separate co2 from mixture of air gases or a sample of gases.after, fabrication of membranes from various percentage of nano-graphene oxide by casting with constant amount of brominated poly (2,6-diphenyle – p – phenylene oxide) , the test of permeation is done and the best mixture for separation is achieved from data and diagrams.
