The micellar catalytic field was proposed in surfactant medium by investigating the complexation between p-nitro-o-carboxylbenzeneazo-8-aminoquinoline (NCBAAQ) and Co(II) at pH 8.8. The cationic surfactant, cetyl trimethylammonium bromide (CTAB) was added and the aggregation of NCBAAQ on CTAB obeys the Langmuir isothermal adsorption. The enrichment of NCBAAQ on CTAB micelle resulted in a sensitive and rapid complexation of NCBAAQ with Co(II). The ternary complexation was characterized by the microsurface adsorption spectral correction (MSASC) technique. Results showed that the complex Co3NCBAAQ12CTAB78 is formed.
