摘要：

Complexation of two cationic styryl dyes containing aza-15-crown-5 moiety and Na+, K+, Ca2+ and Ba2+ was investigated spectrophotometrically in water-containing acetonitrile medium. The ligand/complex ratio was estimated using a method for resolution of overlapping bands. A model for evaluation of the water action is proposed and stability constants were calculated for all metal ions in question.
