Rheology of humic gel

Abstract

The main aim of the bachelor thesis was to test several modifications of humic hydrogels’ preparation method and to discuss their effects on mainly viscoelastic properties of resulting materials. Main conditions, tested in the experimental part, were presence of acidic impurities from the gelation step in the gel and an addition of cations with a higher valence during or after the preparation step. The most important evaluated parameters of the materials were inner pH, solid content and mainly basic viscoelastic characteristics
