BIOSURFACTANT-ENHANCED SOLUBILIZATION OF NAPL MIXTURES

BAI G. / MAIER R. M. / MCCRAY J. E. / et al. - ARTICLE DE PERIODIQUE - 2001

Theory of solubilization of napl mixtures in water. Experiments with acid form of dirhamnolipid (dr-a)are made with batch solubilization experiments. Discussion on biosurfactant-enhanced apparent solubilities for the two-components napl at various concentrations. Summarization of the measured and ideal apparent solubilities of toluen, ethylbenzene and buthylbenzene. The unifac model is used for estimating activity coefficients in liquid-liquid equilibria. Predicted versus measured biosurfactant micelle-water partition coefficients are compared.
