AbstractBromophenol blue (BB), an anionic dye, was removed from aqueous solution by solvent sublation of a BB hexadecyl-pyridium-chloride (HPC) complex (sublate) into isopentanol. A stoichiometric amount of surfactant (surfactant-dye = 2:1) was the most effective compound for the removal, with over 95% BB removed from the aqueous solution in 10 minutes by solvent sublation. The removal rate was somewhat enhanced by high airflow rates and was also more or less independent of the organic solvent volume floated on the top of the aqueous column. The effects of electrolytes (e.g. KCl), nonhydrophobic organic compounds (e.g. ethanol), and pH of the solution upon the process were studied. The infrared spectra showed that the interaction between sublate and organic solvent was weak. The comparison of air stripping and solvent extraction with the solvent-sublation process was made. The solvent-sublation process was consistent with first order kinetics. A characteristic parameter, apparent activation energy of attachment of the sublate to bubbles, was determined as 4.77 KJ/mol.; Bromophenol blue (BB), an anionic dye, was removed from aqueous solution by solvent sublation of a BB hexadecyl-pyridium-chloride (HPC) complex (sublate) into isopentanol.
