摘　　要：研究了在微乳液介质中深亚铜灵与亚铜显色反应的条件。络合物的最大吸收波长λｍａｘ＝４７７ｎｍ，铜量在０～６５μｇ／２５ｍｌ的范围内符合比尔定律，表观摩尔吸光系数ε＝１．３×１０４，并且在水相中可直接进行光度测定。该法用于合金中微量铜的测定，结果较好。The colour reaction of Cu(I) with Bathocuprolin in microemulsion has been studied.Its apparent molar absorptivity is 1.25×10 4L·mol -1 ·cm -1 at 477nm.Beer’s law is obeyed in the range of 0-65μg/25ml for Cu(Ⅰ).Satisfactory results were obtained for the determination.
