Embodiment 1
[0023] Step1: Add starch wastewater from potatoes and sodium hydroxide or potassium hydroxide (100mL: 1.0-1.3g) into the reaction kettle to make the pH value reach 9, and heat until the mixture boils;
[0024] Step2: Add mineral humic acid into the boiling mixed solution according to the ratio of mineral humic acid: mixed solution = 1g: 3.5mL, heat and stir.
[0025] Step3: Control the temperature of the reactor at 95°C, keep it for 3 hours, then lower the temperature to 80°C, and keep it for another 3 hours.
Embodiment 2
