The process of Cr (VI) complexation of modified carbon fibers was studied. Modified carbon fibers were obtained by the liquid-phase oxidation
of the concentrated nitric acid and diphenyl carbazide solution impregnation. The morphology of starting and modified fibers surface was studied
using atomic-force microscopy. Sizes of complexes formed in the process
of interaction of chromium with the functional and analytical group of the
diphenyl carbazide chelating reagent, was established.
