在pH 2.00～3.42的B-R缓冲溶液中,罗丹明6G与十二烷基苯磺酸钠(SDBS)、十二烷基硫酸钠(SDS)阴离子表面活性剂反应形成离子缔合物,导致共振瑞利散射(RRS)增强,并产生新的RRS光谱,最大RRS峰位于375 nm,方法对SDBS、SDS的检出限分别为6 ng/mL、5 ng/mL,其线性范围分别为0.02～5.6 μg/mL、0.02～14.0 μg/mL.研究了适宜的反应条件,方法具有较高的灵敏度,用于合成水样和环境水样中阴离子表面活性剂含量的测定,结果满意.

In pH 2. 00-3. 42 Britton-Robinson（B-R） buffer medium, Rhodamine 6G can react with sodium dodecylbenzene（SDBS） and sodium dodecyl sulfate（SDS） to form ion-association complexes. As a result, an enhanced resonance rayleigh scattering（RRS） spectra was observed, and the maximum RRS wavelengths of ion-association complexes were located at 375 nm. The detection limits of SDBS and SDS were 6 ng/mL and 5 ng/mL, and the linear ranges were 0. 02 - 5. 6 and 0. 02 - 14. 0 μg/mL, respectively. The method has been applied to the determination of SDBS and SDS in ...
