离子表面活性剂对Triton X-100浊谱性质的影响

EFFECT OF IONIC SURFACTANTS ON CLOUDINESS-SPECTRUM PROPERTY OF TRITON X-100

本文研究离子型表面活性剂(十二烷基硫酸钠,SDS;十六烷基溴化吡啶,CPB)对Triton-100浊谱性质的影响。实验结果表明SDS或CPB的加入生成了混合胶团,导致起始浊点、终止浊点和最大光散射强度的变化,进一步探讨了1:1 SDS-CPB混合表面活性剂对浊谱曲线的影响,提出了TX100-SDS-CPB三元混合胶团模型,并初步验证了这一结果。

The effects of ionic surfactants (sodium dodecyl sulfate, SDS; and cetylpyridine bromide, CPB) on cloudiness-spectrum properties of TritonX-100 were studied. The experimental results indicate that mixed micelle formed by adding in SDS or CPB makes ti, tf and VZ (max) increasing. The effect of 1:1 SDS-CPB mixed surfactants on cloudiness-spectrum curves was further examined. By experimental results, we described the model of SDS-CPB-TX100 trinary mixed micelle and preliminarilyverified this hypothesis.
