Regeneration and long-term chemical stability of heterogeneous anion exchange membrane in perchloric acid

Popis výsledku v původním jazyce

Drinking water quality has been a global problem in recent years. With the growing specific industry, groundwater and surface water are contaminated with certain substances, so drinking water concentration limits for other substances must be defined. Fortunately, with the evolving industry, there is a range of methods that can be used to clean drinking water. One is also an electromembrane process with anion exchange membranes. These membranes can be used, among other things, to remove perchlorate ions from drinking water. The paper deals with regeneration and long-term stability of anion exchange membranes in 3% perchloric acid solution. For anion exchange membranes, electrochemical properties as areal resistance and permselectivity were observed for 5 months. At the same time, a change in the mechanical and optical properties of the reinforcing fabrics used in the anion exchange membranes was monitored. Long-term exposure did not have a major effect on the anion exchange membrane permselectivity, and the mechanical properties of the reinforcing fabric did not show significant changes. Differences were determined only for areal resistance, which grew slightly with increasing exposure time.
