Solvent sublation, an adsorptive bubble technique, was used to remove a taste and odour causing hydrophobic organic, viz. 2.3,6-trichloroanisole from aqueous solution. Considerable Improvement over conventional floe bubble air stripping operations was observed. The effects of organic to aqueous phase volume ratio, the air flow rates, interferences from electrolytes upon the separation rate, and the effects of nonhydrophobic organics (e.g. ethanol, propanol) were studied.
