Let’s calculate the exchange capacity of the chlor-alkali membranes that are being used The exchange capacity of chlor-alkali membranes is a very important parameter, but it doesn’t seem to have been discussed specifically in this section... haha. If anyone knows, please let me know. # ， ， &
There isn’t a single person who’s participating in the discussion... 55555555
The ion exchange capacity of an ion-exchange membrane refers to the number of millimoles of ions that can be exchanged equally per gram of dry membrane (anion-type or cation-type) or wet membrane (hydrogen-type) with the corresponding ions in the external solution. Ions are an important parameter that determines the performance of ion membranes, almost from morning to night. Membranes with a high exchange capacity exhibit good electrical conductivity; however, due to their higher hydrophilicity, their water content is also high, which allows electrolyte solutions to penetrate the membrane and reduces its selectivity. Conversely, membranes with a lower ion exchange capacity have higher resistance, but they also exhibit better selectivity.
