聚氧乙烯醚型非离子表面活性剂TritonX-100水溶液的浊谱性质

本文研究烷基酚聚氧乙烯醚型非离子表面活性剂TritonX-100水溶液的浊谱性质。得到了与脂肪醇聚氧乙烯醚非离子表面活性剂AEO9相类似的典型浊谱曲线以及浊度-浓度线性关系区间,发现TritonX-100水溶液同样具有反常浊谱行为。首次研究了表面活性剂浓度对起始浊点、最大浊度值的影响,发现上述关系曲线在浓度为500×10~(-6)时存在一致的拐点,初步解释了这种现象。同时研究了升温速率对其浊谱特性的影响。

CLOUDINESS-SPECTRUM PROPERTY OF POLYOXYETHYLENE ETHER NONIONIC SURFACTANT TRITON X-100 AQUEOUS SOLUTION

The cloudiness-spectrum properties of alkylphenol polyoxyethylene ether nonionic surfactant TritonX-100(TX100)aqueous solution were studied. We have obtained the classic cloudiness-spectrum curves at different concentration and cloudiness vs concentration linear district which is similar to other nonionic surfactants AEO9 and TX10. The anomalous behavior of cloudiness-spectrum of TX100 was also discovered. At the same time, We first studied the effects of surfactant concentration on ti and VZ(max). For these two curves, there exists a inflection point at same 500×10-6 concentration. Finally,the effect of different temperature-increasing rates on cloudiness-spectrum properties was examined.
