Abstract
Darba ietvaros ir izgatavotas sulfonētas poliēterēteraketona membrānas ar dažādām sulfonēšanas pakāpēm. Patieso sulfonēšanas pakāpi ieguva, izmantojot titrēšanas metodi. Virsmas dzeta potenciāla noteikšanai izmantoja plūsmas potenciāla mērījumus. Izmantojot SurPASS™ 3 instrumentu, dzeta potenciālu aprēķināja no eksperimentu laikā izmērītajām spiediena un plūsmas potenciāla izmaiņām.
As part of the work, sulfonated polyetheretherketone membranes with different degrees of sulfonation have been produced. Real degree of sulfonation was obtained using the titration method. Streaming potential measurements were used to determine the surface zeta potential. Using the SurPASS ™ 3 instrument, the zeta potential was calculated from the changes in pressure and flow potential measured during the experiments.
