Adsorption mechanism of alkyl polyglucoside (APG) on calcite nanoparticles in aqueous medium at varying pH

An initial adsorption of APG on CCNP surface seemed to be occurred due to the van der Waals force. An initial surface charge influenced determination of a major driving force, which resulted in hydrogen bonds (pH 7) and the hydrophobic interaction (pH 10) as a main sources of adsorption of APG on the CCNP surface. The difference in adsorption structure caused difference in improvement of dispersion stability of CCNPs in an aqueous medium.294
