Original Abstract

The permeability and barrier properties of various solutes were studied through nanoporous alumina membranes by diffusion cell technique. Fabricated membranes were characterized by basic physic-chemical methods. The accurate thickness and roughness was determined by profilometry, the distribution of pores and pore size was detected by mercury intrusion porosimetry, textural properties were studied by scanning electron microscopy and specific surface area by BET analysis. The specific permeability was compared by determination of fundamental diffusion parameters such as diffusion flux and break-through time (lag time). Results show, that the penetration ability and other important parameters such as thickness and the distribution of pores are strongly dependent on experimental setup within preparation of nanoporous alumina membranes. The most important parameters which influenced the final properties of membranes are time of anodization, type of electrolyte, applied voltage and current density.
