THIONIN DERIVATIVES IN THE EXTRACTION AND DIRECT PHOTOMETRIC DETERMINATION OF BORON
Thionin and nine commercially available thionin derivatives were studied for their applicability in the analytical solvent extraction and direct photometric determination of boron. Azure A, Azure B, Azure C, Methylene Blue, New Methylene Blue N, Methylene Green, Toluidine Blue O, Thionin, and the eosinates of Azure A and B were investigated. Over thirty organic solvents, mostly chlorinated or brominated were tried with these dyes. 1,2-Dichloroethane, 1,2-dichloropropane, dichloromethane, 1, 1,2-trichloroethane, cis- dichloroethylene, o-dichlorobenzene, 1,4dichlorobutane, and mixtures of these solvents proved applicable. Many good dye-solvent combinations were found which were very attractive for the separation and determination of various amounts of boron. Only thionin itself proved unsatisfactory. (auth)
