Micellar solubilization of unsaturated hydrocarbon concentrations as evaluated by semiequilibrium dialysis
Article Abstract:
A study has been conducted to assess the solubilization potentials of unsaturated hydrocarbon under steady-state conditions using semiequilibrium dialysis. Analysis of dialysis cells indicated that the micellar core and palisade layer influences the solubilization of hydrocarbons of varying polarity. Testing of hydrocarbon contaminants revealed increased micelle-water partition coefficient for naphthane, decreased for naphthanol and remained constant for naphthalene. This suggests that as the mole fraction of hydrocarbons in the micellar core increases, the faster the solubilization.

Application of boron isotopes for identifying contaminants such as fly ash leachate in groundwater
Article Abstract:
The feasibility of using boron isotopes for determining the concentration of fly ash leachate contaminant in groundwater is evaluated. Experiments are conducted wherein water samples are diluted with artificially produced leachate. The solution is then treated with boron extracted from an aqueous solution. Results show that boron isotopes are very useful in measuring the amount of leachate in groundwater from environments having unique boron isotopic value.

Isolation of marine sediment colloids and associated polychlorinated biphenyls: an evaluation of ultrafiltration and reverse-phase chromatography
Article Abstract:
Colloids are one of the three phases of natural waters and assist in sediment transport. In marine systems, colloids have been confirmed to enhance the transport of organic contaminants. Experiments using ultrafiltration and reverse-phase chromatography provide evidence that environmental colloids also have effects on the geochemistry and bioavailability of nonpolar organic contaminants such as polychlorinated biphenyls.
