Wd. Clemens et al., CONCURRENCE OF SOLUBILIZATION AND ADSORPTION IN MULTICOMPONENT SUSPENSIONS OF LAYER SILICATES, Langmuir, 10(5), 1994, pp. 1366-1369
Interaction of different components can lead to synergistic or antagon
istic effects in complex systems. The influence of surfactants on the
transport properties of hazardous chemicals such as polycyclic aromati
c hydrocarbons (PAH) in soil is considerable. Depending on type and co
ncentration, surfactants may favor the immobilization or remobilizatio
n of PAH. The decrease of adsorption and the amount of solubilization
above the critical micelle concentration (cmc) can be enhanced by addi
tion of oil. The results obtained by a new fluorescence spectroscopic
method show that microemulsions might be useful in soil remediation pr
ocesses.
