| Summary: | although, some uncertainty in the analysis exists. an inverse relationship to water solubility. Predictions analysis or BPLC analysis. The total extraction for the and an empirical correlation based on octanol-water aqueous phase, Ki. increased as the water solubility of the coefficients which compared well to values in the components decreased. Ki also increased as pressure consistently low. It seems that both the additional consistently yielded mass balance closures over 100%. It contaminants and the soil organic matter are acting as entrainers to facilitate extraction. The predicted values equilibrium distribution of the mixture and of the experiments, the distribution between the SCF phase and the extracted by the supercritical C02, the water, and the extractions of a complex phenolic mixture were analyzed by from the two phase system of water-CO2 yielded values of Ki in closing the mass balance and yielding distribution increased. The partition coefficient between the soil and individual components were determined. A single stage batch Kd, the predicted percent extractions were reasonable. The literature. The three phase experiments, however, of Kdwere significantly lower than those for the three on two phase experimental data for the system of soil-CO2 partition coefficients. These predictions were reasonable; phase experimental data and theoretical correlations. The phase, but because the model is more sensitive to Ki than phenolic mixture. A four component phenolic mixture was polynuclear aromatic hydrocarbons (PAHS) was predicted based soil-water slurries. The extent of extraction and the successfully extracted from two phase and three phase Supercritical C02was used to extract orgamc rruxtures from systems and analyzed by BPLC. For the three phase system the water, Kd, decreased as temperature increased and showed three phase distribution for the extraction of a mixture of three phase system of soil-water-CO2 was predicted from two TOC. The two phase extractions from water were successful vessel was used to perform the extractions, and analyses was determined that the soil organic matter was being were performed using either total organic carbon (TOC) which compared well to those for the three phase, but were |
