Vliv teplotních a cyklických změn pH na geometrii vybraných iontovýměnných membrán

Abstract

The bachelor's thesis deals the effect of temperature and cyclic pH changes on heterogeneous ion exchange membranes. The aim of the experimental tests was to monitor the dimensional changes of these membranes. The theoretical parts are processed literature search on the topic of membrane processes - their description, division, production and division of membranes. The practical part describes the methodology of experiments and a description of the tested membranes. A total of 7 membrane samples from three manufacturers were tested. From the point of view of operating conditions, it is important to know how the ion exchange membrane behaves after swelling and what are its critical operating conditions.
