FIG. 38 Electrokinetic potentials of quartz capillaries (r=7.2 µm) equilibrated with PEO solutions of various concentration C in

ABSTRACT

After establishment of an equilibrium adsorption layer of PEO at small pressure differences (2.5 to 3 atm), the influence of flow rate of the same solution was studied. For this purpose, measurements were performed at increasing pressure differences ∆P, up to 60 atm.
