研究了以阴离子型微乳液SDS/n-C_4H_9OH/n-C_7H_(16)/H_2O为介质时对铬天菁S(CAS)-Al体系吸收光谱的影响,以及阳离子表面活性剂CTMAB对SDS微乳液体系的增效作用。结果表明:以O/W型SDS微乳液为介质时,对CAS-Al体系有增敏作用;以O、W双连续型SDS微乳液为介质时,随微乳液含水量的减少,λ_(max)紫移,Aλ_(max)减少;以W/O型SDS微乳液为介质时,随微乳液含水量的减少,λ_(max)值与Aλ_(max)值又上升,但无增敏作用。CTMAB单独存在时对CAS-Al体系的增敏作用并不明显,但CTMAB对SDS微乳液体系却有明显的增效作用。
The effect of the anionic microemulsion SDS / n-C_4H_9OH / n-C_7H_ (16) / H_2O on the absorption spectra of S-CAS was investigated, and the effect of cationic surfactant CTMAB on the adsorption of SDS microemulsion System synergy. The results showed that: when O / W SDS microemulsion was used as a medium, it sensitized CAS-Al system; when O, W bicontinuous SDS microemulsion was used as media, with the decrease of microemulsion water content, λ max ) And purple (Aλmax) decreased. When W / O SDS microemulsion was used as medium, the values of λ max and A λ max increased with the decrease of water content of microemulsion, but no sensitization. The sensitizing effect of CTMAB to CAS-Al system alone was not obvious, but CTMAB had obvious synergistic effect on SDS microemulsion system.
