Aldrich humic acid was separated into humin, humic acid, and fulvic acid. These fractions and the unfractionated humic material were wet digested and analyzed for Cu, Cd, Cr, Fe, Mn, Ni, Pb and Zn by atomic absorption. Solid samples and digests were also analyzed for manganese by neutron activation.
