Abstract:
     The high-activity humic acid contains active humic acid 45-60 wt%, and has ash content 10-30 wt%, water insoluble matter less than 12 wt%, wtaer content less than 15 wt% and its pH value is 9-11. It is produced by using active leonardite in liquid state and through reinforced activation of various active radicals in humic acid and subsequent concentration and refining. Using the present invention can produce various humates, and the humic acid and its salts have high adsorption, high viscosity, good complexation and wide application range.
