논문 초록 (Abstract)
The performances of aqueous mixtures of the model nonionic surfactant Triton X-100 (TX100) and chitosan (CS) for the solubilization of the hydrophobic organic compound phenanthrene (PHE) were evaluated by varying mixture compositions. The addition of minute amounts of C S into TX100 solutions above the critical micelle concentration signific antly increased PHE solubility.The PHE solubility was maximized at cer tain optimal concentrations of CS increasing in proportion to the TX10 0 concentrations, which were 2, 10, and 20 mg/L CS for 5, 10, and 2 0 g/L TX100, respectively. At each optimal concentration of CS, PHE solubility was increased by 46%, 39%, and 43% for the 5, 10, and 20 g/L TX100 solutions, respectively. The enhanced solubilization o f PHE by the addition of CS to TX100 solutions may be attributable to multiple factors, such as an increase of micellar size and hydrophobi city as well as to the formation of variously configured micelle-pol ymer aggregates.
