建立了二级散射光谱法测定阴离子表面活性剂的新方法.研究了阴离子表面活性剂SDBS与健那绿离子缔合物的二级散射和"反二级散射"光谱.结果表明:当λem=340 nm,λex=680 nm时,在0～50 μg/mL质量浓度范围内,ΔIFDS与溶液中物质的质量浓度成正比,线性相关系数为0.9988,检出限为17.4 ng/mL.

A method for determination of anionic surfactants by second-order scattering detection was proposed. The spectra of second-order scattering(SOS) and frequency-doubling scattering(FDS) for dodecylbenzene sulfonic acid sodium salt(SDBS)-Janus green system were studied. The results indicated that the scattering light intensity was proportional to the concentration of SDBS at λ_(em)=340 nm, λ_(ex)=680 nm and the linear range of its concentration was 0～50 μg/mL. The correlation coeff...
