Description
Summary:Nanofiltration membranes were modified using Layer-by-Layer method. Different number of polycation/graphene oxide bilayers was deposited on the surface of the membranes. The structure of modified membranes was studied under optical microscope. The structure of graphene oxide was investigated using transmission electron microscopy and dynamic light scattering. The experimental properties of modified membranes were determined using acriflavine solution in a bench scale setup. The retention of the membranes increased with an increasing number of bilayers to a point, similar to a saturation curve. The flux of the permeate decreased slightly, converging to a lower limit with increasing number of bilayers. The results show that nanofiltration membranes can be effectively modified using polycation/colloid particle bilayers.
