Abstract/OtherAbstract:
A pulse polarographic method for the analysis of humic acids fractionated by gel permeation chromatography is described. It is concluded that the pulse polarography of the nitroso-derivatives, already reported as an analytical method for the determination of humic acids, really gives responses due to the presence of iron in the samples. Atomic-absorption measurements confirm this conclusion quite unambiguously.
