논문 초록 (Abstract)
The solubility of solid phenanthrene (PHE) powder in aqueous solutions of surfactant and chitosan (CS) was evaluated by varying the composition of aqueous mixtures. Cetyltrimethyl ammoniumbrom ide (CTAB) and sodium dodecyl sulfate (SDS) were used as model cationic and anionic surfactants, respectively. CS at a particular concen tration in the mixture especially above the CMC value of the anionic su rfactant exhibited somewhat higher PHE solubility values than surfact ant itself. CS (20 mg/l)-SDS (20 g/l) solution showed higher PHE solubil ity (422.05 mg/l) than that of 20 g/l SDS (377.92 mg/g). However, CS-CTA B didnot show any additional enhancing effect on PHE solubilization, and CS (5 mg/l)-CTAB (10 g/l) solution showed almost similar PHE solu bility (867.23 mg/l) of 10 g/l CTAB (865.25 mg/g). The maximum inc rease in absorbance value of a 20 ml CS solution (5, 20 and 100 mg/l ) at 540 nm with stepwise addition of SDS (10 g/l) was found at a SDS c oncentration much less than its CMC value (2.33 g/l) in the mixture, ind icating strong complex formation between CS and SDS because of oppo sitely charged molecules in the experimental conditions.
