摘要
以含水量为９４．１％的非离子型乳化剂ＯＰ／ｎ－Ｃ５Ｈ１１ＯＨ／ｎ－Ｃ９Ｈ２０／Ｈ２Ｏ微乳液为介质，进行了Ｃｕ（１１）－二甲酚橙ＯＸ分光光度法研究（ε＝３．６×１０４Ｌ·ｍｏｌ－１·ｃｍ－１），与以水为介质（ε＝５．２×１０３Ｌ·ｍｏｌ－１·ｃｍ－１）及相同含水量的乳化剂ＯＰ胶束介质（ε＝１．１４×１０４Ｌ·ｍｏｌ－１·ｃｍ－１）相比较，测定灵敏度显著增加，样品分析结果令人满意。
The spectrophotometric determination of Cu is studied with Xylenol Orange (OX) in OP/n-C5H11OH/n-C9H2O/ water microemulsion medium (water content of 94.1%). The sensitivity (ε=3.6×104L·mol-1·cm-1)is increased in comparison with that got from water medium (ε=5.2×103L· mol-1·cm-1)and from OP medium (ε=1 14× 104L·mol-1·cm-1).The results of sample analysis are satisfactory.
