Effect of Graphene Oxide on the Permeability of Asymmetric Polysulfone Membranes
摘要
Abstract
Membranes have been prepared from polysulfone and graphene oxide with mass concentrations from 0 to 0.4%. A series of experiments were conducted to study the permeability of the obtained samples at pressures of 10, 15, and 20 atm. The experimental time dependences of the permeated water volume at a constant pressure were obtained. The dependence of the membrane permeability on the graphene oxide concentration and pressure was calculated. Conclusions were drawn about the influence of graphene oxide concentration and pressure on the permeability of the samples.
