摘　　要：本文研究了以微乳液为介质时，铜与ＤＤＴＣ的显色反应。该体系的最大吸收波长为４４０ｎｍ，其表观摩尔吸光系数ε为１．３×１０＾４，铜量在０－０．３μｇ／ｍＬ范围内符合比尔定律，该法适用于测定汽油中添加剂环烷酸铜。The color reaction between copper and DDTCin micro-emulsions has been studied.The maximum absorbance occurs at 440 nm,and its apparent molar absorptivity is 1.3x 10￣4 L. mol￣(-1).cm￣(-1).Beer's law is obeyed in the range of 0～3μg/mL for copper.The method has been proposed for the determination of copper naphthenate in gasoline.
