super(13)C-NMR analysis of components of chernozem humic acids and their fractions with different molecular sizes and electrophoretic mobilities

Tandem size-exclusion chromatography and polyacrylamide gel electrophoresis were used for obtaining stable fractions of different molecular sizes and electrophoretic mobilities from chernozem humic acids (HAs). The obtained fractions were analyzed using solid-phase super(13)C NMR. The tendencies of...
