New Express Technique for Determination of Antioxidant Activity of Humic Substances

摘要

Interest of analytical chemists to humic substances (HS) is instantly growing. First of all, it is connected to the current trend in agriculture directed toward application of organic and organic-mineral fertilizers and necessity in the corresponding quality control techniques. Another reason is that humic substances bind toxicants and cause disturbing impact on their determination in air, water, and soil. This research is devoted to a use of amperometric technique for determination of humic and fulvic acid. These natural compounds contain phenolic units that makes feasible amperometric detection.
