Abstract

- Adsorption of anionic polymeric surfactants on silica-modified Fe2O3 pigment with negative zeta potential.
- This is due to the presence of positive oxydic iron sites.
- Styrene oxide-ethyleneoxide-PO42− (SO-EO-P) adsorbs, only caused by electrostatics.
- Polyacrylic acid sodium salt (PANa) also adsorbs; not lowered by SO-EO-P.
- SO-EO-P adsorption is lowered by PANa.
