十六烷基三甲基氯化铵与直接蓝199的相互作用
Interaction Between Cetyltrimethyl Ammonium Chloride and C.I.Direct Blue 199
摘要
Abstract
The interaction between an anionic dye,C.I.direct blue 199 (DB199) and cetyltrimethyl ammonium chloride(CTAC) was investigated by conductivity testing and spectrophotometry.The experimental results revealed that when the concentration of CTAC was less than the critical miscelle concentration(CMC),the conductivity curve of the mixed solution is basically consistent with the theoretical values.When the concentration of CATC was higher than the CMC,approximately 80.88％ of the Clˉ was adsorbed on the surface of micelles,and it would can drop to 78.48％ when dyes were added into the solution.The CTAC surfactant would can cause a hypochromic shift of the maximum absorption wavelength firstly and red-shift with the increase of surfactant concentration.As the surfactant concentration increases,the absorption intensity is first decreased and then increased.关键词
