The influence of ions of various compositions and valences on the charging and aggregation processes in dispersions of nano or colloidal particles has been in the focus of numerous researchers for a long time. These phenomena can be described by the Hofmeister series of ions and the Schulze-Hardy rule for mono and multivalent electrolytes, respectively. However, due to the relevance of this issue in biomedical (e.g., drug delivery in biofluids), environmental (e.g., wastewater treatment) and other industrial (e.g., papermaking) applications of particles, this topic attracts widespread contemporary interest. We study the destabilization power of simple inorganic anions and cations (e.g., Cl-, CO32-, PO43-, Na+, Ca2+ and La3+) in dispersions of nanoparticles and their composite materials. A novel direction in this research is the application of pure of hydrated ionic liquids as dispersion medium.
