乙酸丁酯、磷酸三丁酯均是工业中常用的萃取剂,加入表面活性剂后,它们在水中的溶解度会有较大增加.通过对水中的乙酸丁酯、磷酸三丁酯的定量分析可以为研究萃取剂的流失机理提供数据,从而指导生产.常用的气相色谱分析方法是用有机溶剂萃取后,对有机相进行分析.但由于某些表面活性剂存在,加入有机溶剂会产生乳化,产生较大误差.对此本文采用毛细管气相色谱法研究建立了对含有阴、阳离子,非离子表面活性剂水溶液中的乙酸丁酯、磷酸三丁酯的定量方法,结果表明,这是一种快捷、准确、简便的分析方法.
Butyl acetate, tributyl phosphate are commonly used in industry extractants, adding surfactants, their solubility in water will have a greater increase by water on the butyl acetate, tributyl phosphate quantitative analysis of To study the mechanism of extractant loss mechanism to guide the production of gas chromatography commonly used method is to use organic solvent extraction, the organic phase analysis.However, due to the presence of some surfactants, organic solvents will produce emulsification, resulting Larger error.In this paper, capillary gas chromatography was used to establish a quantitative method for the determination of butyl acetate and butyl phosphate in aqueous solutions containing anionic, cationic and non-ionic surfactants.The results showed that this method is a fast, Accurate and simple method of analysis.
