The solubility of phenol, 4-chlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, 2-nitrophenol, and 4-nitrophenol, was measured in aqueous solutions containing small concentrations of electrolytes or surfactants in the temperature range from 280 K to 345 K. The experimental determination of the solubility was performed using a light transmission technique. The results show that small amounts of surfactants or electrolytes can modify significantly the aqueous solubility of these compounds.
