Abstract
The interaction between the cationic dye, thionin(Th) and the anionic surfactant, sodium dodecyl sulfate (SDS) has been investigated by absorption spectra. As the temperature of surfactant solution was increased in premicellar range(S/D=10, 80, and 160) which was much lower than the critical micelle concentration(CMC), the increment or decrement of the molar extinction coeffecient ratio appeared. It was found that the most stable temperature range of the oligomer aggregate in Th-SDS system at S/D=160 was below
양이온 색소인 thionin(Th)과 음이온 계면활성제인 sodium dodecyl sulfate(SDS) 사이의 상호작용을 흡수 spectra로 고찰하였다. 임계미셀농도(critical micelle concentration, CMC)보다 훨씬 낮은 premicellar 영역(S/D=10, 80 및 160)에서 온도가 증가함에 따라 몰 흡광계수비가 증가하거나 감소함을 볼 수 있으며, S/D=160에서 Th-SDS계의 다분자 회합체가 생성하는 가장 안정한 온도 범위는
