The effect of alkali metal chlorides on the metachromatic behaviour of Trimethyl propyl thionine (TMPT) and Diethyl methyl propyl thionine (DEMPT) as induced by polyacrylic acid (PAA) was investigated spectrophotometrically. The size of hydrated ion and hydrophobicity of substituents were not found to be significant factors to influence the above behaviour. The alkali metal cation affinity sequence was observed as Li+ > K+ > Cs+ for polyacrylic acid exchangers. A large amount of destruction of metachromasy was observed in PAA-TMPT and PAA-DEMPT on addition of small amounts of cetyl trimethyl ammonium chloride (CTACI) and Decyl trimethyl ammonium chloride (DTACI) and their order CTACI > DTACI.Downloads
