WATER-SOLUBLE HUMIC ACIDS, A METHOD OF OBTAINING THEM, A METHOD OF DETOXIFYING LAND AND EFFLUENT SEDIMENTS, AND A METHOD OF RECULTIVATING AGRICULTURAL LAND WITH THE AID OF THE PROPOSED WATER-SOLUBLE HUMIC ACIDS

摘要

The pH and moisture values of the proposed water-soluble humic acids, which have mean molecular weights of 5000-100,000, are given by the formula W » 100 - 25 (pH - 2), where 2 pH « 6. A method is proposed for obtaining water-soluble humic acids, as well as a method of detoxyfying land containing toxic and radioactive substances, a method of detoxifying effluent sediments containing heavy metal cations, and a method of recultivating agricultural land containing toxic substances.
