Embodiment 1
[0014] Take 300mL of berberine hydrochloride solution with a concentration of 400mg / L in a 500mL beaker, add NaNO 3 , so that the concentration of nitrate in the solution is 0.1, 0.5, 1.0, 2.0mmol / L, then add humic acid to make the concentration 2mg / L, add hydrogen peroxide to make the concentration 1mmol / L, and place it in the photodegradation reaction In the equipment, react for 3h. Take out the beaker after the reaction finishes, and measure the berberine hydrochloride content in the solution. The results are shown in Table 1.

Embodiment 2
[0018] Take 400mg / L berberine hydrochloride solution 300mL in a 500mL beaker, add NaNO 3 1.0mmol / L, add humic acid respectively, so that the concentration of humic acid in the solution is 2, 5, 8, 10mg / L, then add hydrogen peroxide to make the concentration 20mmol / L, and place it in the photodegradation reaction equipment , Reaction 3h. Take out the beaker after the reaction finishes, and measure the berberine hydrochloride content in the solution. The results are shown in Table 2..

Embodiment 3
[0022] Get the berberine hydrochloride solution 300mL that concentration is 400mg / L in 500mL beaker, add sodium nitrate and make its concentration be 1.0mmol / L, add humic acid and make its concentration be 5mg / L, add hydrogen peroxide (30% peroxide) again Hydrogen peroxide solution), so that the concentration of hydrogen peroxide in the solution is 1, 5, 10, 20mmol / L respectively, placed in the photodegradation reaction equipment, and reacted for 3h. Take out the beaker after the reaction finishes, and measure the berberine hydrochloride content in the solution. The results are shown in Table 3.
