Demidova, A. Bulavchenko] Micellar preconcentration of 1 : 2 associates of Bromophenol Blue with cetyltrimethylammonium bromide is proposed to improve the procedure for the spectrophotometric determination of cationic surfactants. The preconcentration procedure involves quantitative extraction by reversed micelles of Triton N-42 in decane followed by the decomposition of the micellar solution with chloroform. The loss of 10−7-10−5 M cetyltrimethylammonium bromide in 5-100-fold preconcentration was not supported by the added-found method (RSD = 3-5%). The determination limit for cetyltrimethylammonium bromide is 2 × 10−7 M. MAIK "Nauka/Interperiodica”, 2005 Demidova M.
