논문 초록 (Abstract)
The impregnation of Triton X-100 (TX100) in chitosan capsules (TCC) via an anionic surfactant gelation method was investigated for the sorption of naphthalene (NAP) from aqueous solutions. Impregnation with TX100 enhanced NAP sorption at all tested concentrations of TX100, ranging from 0.1 to 10 g/l. The highest NAP sorption capacity (68.7 mg/g) wa s obtained at 2 g/l of TX100, a capacity 5.1-fold higher than that of chitosan capsules without TX100 impregnation (CC) (13.4 mg/g). The highest molar sorption ratio of capsule (MSRC) was 12.23 mol NAP/m ol TX100 at 0.1 g/l, which was much higher than the MSRB for beads (0 .70) and the MSRW for the aqueous phase (0.11). Thus, when a nonionic surfactant is present in a hydrogel capsule, the ability of the surfactant to solubilize organic chemicals can be significantly increased compared to the surfactant in water or in hydrogel be ads.
