“…[2][3][4] Also, orange II, ethyl orange, bromochlorophenol blue and Co(III)-5-Br-PAPS were used for the determination of cationic surfactants. [5][6][7] Although these methods showed a big advantage of high sensitivity, solvent extraction is undesirable from the viewpoint of environmental protection, and the methods are very troublesome because of the double extraction of an ion associate of ionic surfactants with the dye. In order to determine surfactants without solvent extraction, Borrego et al described mixed aggregate-based methodology as a new approach to the quantification of surfactants.…”

Here we report that all types of surfactant could be simply and sensitively determined, by directly quenching the chemiluminescence (CL) between luminol and NaIO4 in a basic solution containing one polyhydroxyl compound such as cyclodextrin (CD), glucose or glycerol. This specific quenching effect was attributed to the change of the microenvironment of the CL reaction, caused by the addition of various surfactants. Based on this fact, the potential use of this CL reaction was exemplified by the cationic surfactant CTMAB, anionic surfactant SDS and non-ionic surfactant Triton X-100. It was found that the measurable range of CTMAB, SDS and Triton X-100 were 4.0 x 10(-6)-4.0 x 10(-4) M by using a basic CD-luminol-NaIO4 CL reaction. With our simple setup, CTMAB, SDS and Triton X-100 were detectable at a concentration as low as 2 microM. Overall, this new CL reaction is quite promising for the post-column determination of surfactant mixtures.

“…Furthermore, in water-treatment plants, for human consumption prior determination of the CS concentration may help in the implementation of the purification process. Spectrophotometric methods for CS determination based on the formation of ion pairs with anionic dyes such as Disulphine Blue, Orange II, and Bromophenol Blue have usually been used [11][12][13]. These procedures require an extraction step with an organic solvent such as chloroform, which should be avoided due to its toxicity for life organisms.…”

“…The determination of cationic surfactants in aqueous solutions is very important in process control of cationic surfactants and monitoring of environmental water and so on because of their toxicity to various organisms. Solvent extraction-spectrophotometric methods based on the formation of an ion-pair of the cationic surfactant with an anionic dye such as Orange II and extraction of the resulting ion-pair into a suitable organic solvent such as chloroform have been widely used for the determination of cationic surfactants (Irving and Markham 1967;Scott 1968;Sakai and Ohno 1983;Kasahara et al 1989;Sakai et al 1992). However, the procedures are very complicated and time-consuming.…”

An optical sensing membrane for detection of cationic surfactants was developed. The optical sensing membrane is 2-nitrophenyl octyl ether-plasticized poly(vinyl chloride) membrane incorporating tetrabromophenolphthalein ethyl ester (TBPE). The response of the optical membrane to cationic surfactants was a result of extraction of cationic surfactant into the PVC membrane. The protonated TBPE deprotonates forming an ion associate with the extracted cationic surfactant; simultaneously, the deprotonation of the TBPE is accompanied by a spectral change. Namely, the extracted cationic surfactant changes color of the membrane from yellowish green to blue (absorption maximum: 622 nm). The optical membrane responds to cationic surfactants such as Zephiramine and cetyltrimethylammonium bromide in the concentration range from 1 mM to 100 mM.
