Adsorption of hydroxyethyl cellulose (HEC) and quaternary ammonium substituted HEC (QNHEC) on silica and titanium dioxide has been investigated as a function of pH and electrolyte (NaCl) concentration. Adsorbed amounts have been determined by means o

Measuring soil water potentials is crucial to characterize vadose zone processes. Conventional tensiometers only measure until approximately −0.09 MPa, and indirect methods may suffer from the non-uniqueness in the relationship between matric poten

The intrinsic persistence length of carboxymethyl cellulose (CMC) is determined by size exclusion chromatography in combination with multiangle laser light scattering (SEC-MALLS) as well as from potentiometric titrations. Samples with degree of subst

The adsorption of a weakly cationic polyelectrolyte (poly(dimethylaminoethyl methacrylate), (AMA) and a weakly anionic polyelectrolyte (carboxymethylcellulose, CMC), were studied as a function of pH. As substrates we used the (amphoteric) metal oxide
