In this research, the new separation method based on micro solvent cluster extraction and preferential solvation has been described. A proposed separation method using aqueous mixed solvents of organic solvents (acetonitrile, 1-propanol, 2-propanol and 1,1,1,3,3,3-hexafluoro-2-propanol) or ionic liquids and an open tubular capillary has been separated the model compounds (2-naphthol, 4-nitroani...
