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 these substances must be defined. Fortunately, with the evolving industry, there is a range of methods that can be used to treat water dedicated to potable purposes. Among them, an electromembrane process with anion exchange membranes can be found. These membranes can be used approximately to remove perchlorate ions from purified 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 such as an areal resistance and a 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 the areal resistance, which grew slightly with the increasing exposure time.
