摘　　要：In alkaline conditions,Sodium doecyl sulfate and Bromide hexadecyltrimethyl-ammonium(CTMAB)-Trypan blue(TB) occur faded response to form blue ion compounds.The maximum faded wavelength at 564nm.The apparent molar absorptivities(ε) is 2.73×104 L·mol-1·cm-1.The linear ranges is 0～7.21mg/L.The concentration of Sodium doecyl sulfate in definite range obeys Beer’s law.A new spectrophotometric method for the determination of Sodium doecyl sulfate has been developed.The method was applied to determine the content of the anion surface active agent Sodium doecyl sulfate in landfill leachate with satisfactory results.In alkaline conditions, Sodium doccyl sulfate and Bromide hexadecyltrimethyl-ammonium（CTMAB）-Trypan blue （TB） occur faded response to form blue ion compounds. The maximum faded wavelength at 564nm. The apparent molar absorptivities （ε） is 2.73 × 10^4 L· mol^-1 · cm^-1. The linear ranges is 0 -7.21mg/L. The concentration of Sodium doccyl sulfate in definite range obeys Beer＇ s law. A new spectrophotometric method for the determination of Sodium doccyl sulfate has been developed. The method was applied to determine the content of the anion surface active agent Sodium doccyl sulfate in landfill leachate with satisfactory results.
