[1] Uvarova M. I., Brykina G. D., Shpigun O. A. Phthalocyanine derivatives as mobile-phase modifiers for the indirect detection of fullerenes in high-performance liquid chromatography // Journal of Analytical Chemistry. — 1999. — Vol. 54, no. 3. — P. 224–226. Octadecylsulfamoyl and tert-butyl derivatives of phthalocyanine were studied as mobile-phase modifiers for the indirect detection of fullerenes. It was demonstrated that the sensitivity of determining fullerenes with indirect spectrophotometric detection at 669 nm depends on the nature of the modifier, its concentration in the mobile phase, and the temperature of the column. When the tetra-4-tert-butylphthalocyanine complex of zinc was used as the modifier of the ethyl acetate-acetonitrile (9 : 1) mobile phase, the sensitivity of determining C60 was twice as high as for the direct detection (368 nm). The chromatograms (669 nm) of benzene extracts of graphite black give an estimate of the actual ratio between fullerenes and products of their synthesis and can be used for the rapid determination of the ratio and concentrations of C60 and C70 fullerenes in samples. © 1999 MAEe Cyrillic signK "Hayκa/Interperiodica".
