The constants of the extraction equilibrium and the distribution fordichloromethane as an organic solvent having low dielectric constant of metal cations withchiral Schiff bases, benzaldehydene-(S)-2-amino-3-phenylpropanol (I), o- benzaldehydene-(S)-2-hydroxybenzaldehydene-(S)-2-amino-3-phenyl-propanol (II),amino-3-methylbutanol (III) with anionic dyes [4-(2-pyridylazo)-resorcinol mono sodiummonohydrate (NaPar), sodium picrat (NaPic) and potassium picrat (KPic)] and some heavymetal chlorides were determined at 25 oC. All the ligands have given strongestcomplexation for NaPar. In contrast, similar behaviour for both alkali metal picrates is notapparent in the complexation of corresponding ligands.
