Abstract
It has been shown for the first time that non-ionic ethoxylated surfactants adsorb much less extensively from aqueous solution (at temperatures below their cloud points) on alumina surfaces than on silica surfaces; this is attributed to the formation of surfactant: Al3+ complexes which are stable relative to the surface-adsorbed state.Keywords
