    Abstract: The interaction of two cationic dyes, namely, Azure B (AB) and Pinacyanol chloride (Pcyn) with an anionic polyelectrolyte, namely, sodium carrageenate (NaCar) has been investigated by Spectrophotometric method. The polymer induced metachromasy in the dyes resulting in the shift of the absorption maxima of the dyes towards shorter wavelengths. The s... Show More
