Zeta potential determination of polymeric materials using two differently designed measuring cells of an electrokinetic analyzer
Hermina Bukšek, Thomas Luxbacher, Irena Petrinić
Izvirni znanstveni članek
Oznake: electrical double layer;zeta potential;electrokinetic analyser;streaming current potential;polymeric materials;
The so-called zeta potential can be determined through electrokinetic measurements and indicates the status regarding surface charges along the interface between solids and liquids. Surface charge gives us information about the condition, quality, and characteristics of a macroscopic surface in the ...

Polyacrylic acid (PAA)-coated magnetic nanoparticles (MNP@PAA) were synthesized and evaluated as draw solutes in the forward osmosis (FO) process. MNP@PAA were synthesized by microwave irradiation and chemical co-precipitation from aqueous solutions of Fe2+ and Fe3+ salts. The results showed that th ...
