Description :
Triprlenyl methane dyes are most commonly used in analytical techniques. The addition of surfactants to these also make them useful. Addition of cationic surfactants like Cetyl Pyridinium Chloride (CPC), Cetyl Pyridinium Bromide (CPB) , Cetyl Dimethyl Benzyl Ammonium Chloride (CDBAC), Cetyl Trimethyl Ammonium Bromide (CTAB) in alkaline range results in change in wavelength of maximum absorbance towards acidic range by few units which causes early dissociation of various groups. In this paper the various parameters to study one of Triphenyl methace dye – methyl thymol blue and cationic surfactants and use of these system in simultaneous determination of Thorium, Uranium and Dysprosium is reported.
