| 摘 要： | 采用重量法研究了典型非离子表面活性剂（Tween-20、Tween-40、Tween-60、Tween-80）对以甲苯为代表的挥发性有机污染物（VOCs）的增溶作用.通过计算甲苯在初始和平衡状态的质量变化,确定甲苯在表面活性剂中的增溶量,比较了重量法与传统紫外分光光度法的测定结果,并计算分析4种表面活性剂增溶作用下甲苯...

| Abstract: | In the process of determining the solubilization ability of surfactants by conventional ultraviolet spectrophotometry,the interference can be caused by the surfactants with deep color,and the steps are always complicated.In this paper,the solubilization action of a typical volatile organic compound toluene by nonionic surfactants Tween-20,Tween-40,Tween-60 and Tween-80 through weight method was studied.The solubilization capacity was calculated based on the changes of quality of target compounds,and then th... |
