Abstract:
     Materials including lignin powder, millet flour, wheat bran, vegetable oil, potassium dihydrogen phosphate, rice bran, ammonium bicarbonate, diammonium phosphate, dry yeast and water are placed into reactor, standing at 63-67 deg.C for 90 hr with once stirring each 4 hr, mixed with NaOH to regulate pH value to 12-13, standing at 84-88 deg.C and 1.5 atm for 2 hr with once stirring each 30 min, mixed with HCl to regulate pH value to 6 and separated to obtain liquid, i.e., humic acid. The said process is easy to control and can obtain product with stable quality.
