preparation example Construction
[0033] The present invention provides a kind of preparation method of composite flocculation anti-algae agent, specifically comprises the following steps:
[0034] (1) Dissolving chitosan in acetic acid or hydrochloric acid solution to prepare a 0.1-10 mg / mL chitosan aqueous solution;
[0035] (2) Dissolve an appropriate amount of algae-inhibiting agent in ethanol, and prepare an algae-inhibiting agent ethanol solution of 5 to 200 mg / L, wherein the algae-inhibiting agent is a plant polyphenol with algae-inhibiting efficacy, and the algae-inhibiting agent includes gall One or more of acid, vanillic acid, ferulic acid, catechol and hydroquinone;
[0036] (3) Add an appropriate amount of algastatic agent ethanol solution prepared in step (2) into the chitosan aqueous solution configured in step (1), wherein the volume ratio of the gallic acid solution to the chitosan aqueous solution is (1~3): 1. Then seal the reaction system with plastic wrap, stir and react at 25-30°C for 6-24...
