The effects of many parameters, such as the amount of surfactant, airflow rates, pH, NaCl, ethanol and temperature on the solvent sublation were studied. Experimental results showed that a ratio of surfactant to Pb-dithizone complex (2∶1) was the most effective for the removal, with over 97.4% Pb removed from the aqueous solution in 40 min by solvent sublation, at the value of pH 12.6.The solvent sublation process followed first order kinetics. A characteristic parameter, apparent activation energy of attachment of the sublate to bubbles, was estimated at a value of 2.08 kJ/mol.
