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。
In this paper, the turbidimetric properties of TritonX-100 aqueous solution of alkylphenol polyoxyethylene ether nonionic surfactant were studied. The typical turbidimetric curve similar to AEO9 and the linear relationship between turbidity and concentration were obtained. It was found that TritonX-100 aqueous solution also had anomalous turbidimetric behavior. The effect of surfactant concentration on initial cloud point and maximum turbidity was studied for the first time. It was found that there was a consistent inflection point at the concentration of 500 × 10 ~ (-6), which explained the phenomenon preliminarily. At the same time, the effect of heating rate on the turbidity spectrum was studied.
