Embodiment Construction

[0015] Below in conjunction with specific embodiment the present invention is described in further detail:

[0016] 1. Preparation of berberine·artemisinin compound algaestatic agent

[0017] At room temperature, 600 mg of berberine and 6 mg of artemisinin were dissolved in 1 L of water under the action of magnetic stirring to prepare a berberine·artemisinin compound algicide.

[0018] The artemisinin mentioned above can be selected: 6-7.5 mg.

[0019] 2. Application examples of berberine·artemisinin compound algaestatic agent

[0020] Indoor algae inhibition test:

[0021] Use berberine·artemisinin compound algicide to carry out acute toxicity experiment on aseptically cultured non-toxic Microcystis aeruginosa strain FACHB469, set several concentration gradients, set blank and 3 parallel groups, observe once every 24 hours, Continuous observation for 96h. The results showed that when the net content of berberine·artemisinin in the algae liquid reached above 8.0mg / L, the 9...

Abstract

The invention discloses a berberine. artemisinin composite algicide which mainly contains 600mg / L of berberine and 6-7.5mg / L of artemisinin. The algicide provided by the invention is used for controlling cyanobacterial bloom, when the net content of berberine reaches 10.0mg / L and the net content of artemisinin is more than 0.1mg / L in the pond water, the cyanobacteria amount in the water drops to the 10% of the initial density value after 10 days. The algicide provided by the invention is mainly applied to the prevention and control of harmful cyanobacterial bloom in artificial water systems, lakes, reservoirs, ponds and other freshwater bodies. The composite algicide provided by invention is botanical algicide, and has strong and durable inhibitory effect on algae, no significant impact on other aquatic organisms and no environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of water body pollution control, in particular to a berberine-artemisinin compound algae inhibitor. Background technique [0002] At present, the methods for controlling harmful cyanobacteria in water mainly include physical methods, chemical methods and biological methods. The effect of physical methods is remarkable, but the labor load is large, the effect time is long, the use is more complicated, and the cost is also high; although chemical drugs have quick effects, they are costly, have relatively large toxic and side effects, and have certain residues in water bodies. Long-term use It will cause pollution to the breeding objects, the breeding water body and the surrounding ecological environment; although the biological method has little toxic and side effects, it is often complicated to use, slow to take effect, and difficult to control manually. [0003] Berberine is an active ingredient of the medi...
