| The electrokinetic behavior of micrometer-sized melamine–formaldehyde latex particles in 10−3–10−1 M monovalent electrolyte dispersions was investigated by electrophoresis and electroacoustics. Specific adsorption of the electrolytes was identified as a shift of the isoelectric point (pHiep) with an increased ionic strength. All salts had an equal dependence on the ionic strength. The pHiep was correlated with the anion sequence predicted by the hard–soft acid–base (HSAB) principle, Hofmeister series, and Born charging. The Born and the Hofmeister anion scale were successful in producing a systematic dependency of the isoelectric point (pHiep), particularly in high (10−1 M) and low (10−3 M) MF electrolyte dispersions. No clear trend could be found for the pHiep dependence on the anion HSAB scale. |
