| Abstract | The goal of this research was to characterize the surface properties of nanofiltration membranes. The processes that are used to characterize these membranes are standard but the membranes are synthesized in the laboratory and the applications for these membranes are novel. Several properties will be investigated in detail. These include membrane charge, the surface roughness, and the membrane pore size. The membrane flux and rejection levels are also examined, but are not reported in this paper. The particular focus of this paper is surface charge and roughness of the membrane as well as possible pore imaging and identification. The equipment employed to study the charge of the membrane included an Electro Kinetic Analyzer, used to measure zeta potential (proportional to surface charge) and an Atomic Force Microscope (AFM) with a liquid cell, used to image the morphology of the membrane. This paper also provides background information on the applications and systems which use these membranes. There is good agreement between theoretical and experimental results for such things as the zeta potential. |
