摘要：

An extraction method based on the butanol-water system is used in an improved spectrophotometric determination of Xylenol Orange (XO), Semi-Xylenol Orange (SXO) and Cresol Red (CR) in mixtures. Small amounts of SXO in the presence of much greater amounts of XO, and small amounts of XO in the presence of large amounts of SXO can be determined with good accuracy after extractive separation of the compound to be determined, from the bulk of the other components of the mixture. © 1990.
