A two step degradative procedure for structural studies of aquatic humic acids
Two aquatic humic acids, one from a marine sediment, collected from the Emerald Basin on the Scotian Shelf, the other from a lagoonal sediment obtained from Musquodoboit Harbour, Nova Scotia, Canada, were subjected to oxidative degradation. A two step degradative procedure involving persulfate and permanganate oxidations was used. It appears that persulfate act on the humic molecule by causing the release of peripheral, loosely held materials, whereas permanganate oxidation provides information on the most resistant structures of the humic molecules. © 1990.
