| titleOfInvention | Method for extracting and purifying humus in soil, peat and lignite |
| abstract | The invention discloses a method for extracting and purifying humus in soil, peat and lignite, which comprises the following steps: alkali extraction of soluble humus; (II) acid-soluble alkali-soluble iron-extraction combined humin; (III) acid-soluble alkali-soluble extraction of cosmid binding humins; (IV) separating and purifying insoluble humins. The invention provides a method for extracting and purifying humins systematically, improves and optimizes the method for extracting humic acid and fulvic acid proposed by the national humus association, so that the humins are more suitable for the characteristics of domestic humus sources, and combines the two methods to form a whole set of systematic and integral standard method for extracting various components of humus with different sources and independent intellectual property rights. |
