摘要: AbstractPolyacrylonitrile/titanium dioxide nanofiber (PAN/T-nF) membrane was prepared with TiO2 nanoparticles which dispersed into polyacrylonitrile (PAN) matrix ultrasonic probe in bath. The amount of loaded the 1 and 3 wt% to explore activity membranes adsorption process. PAN/T-nF by electrospinning technique. potential investigated for removal Cr(VI) from aqueous solutions. equilibrium batch process displayed pH dependence maximum took place at 2. attained a contact time 180 min Langmuir model suitable isotherms. Maximum capacities 245.3 280.4 mg Cr(VI)/g were calculated 3% membrane, respectively. on related mechanism surface complexation, coordinat...
