preparation example Construction

[0032] The invention provides a kind of preparation method of algicide base material, wherein, such as figure 2 Shown, described preparation method comprises:

[0033] 1) mixing Artemisia annua and calcium chloride to obtain a mixture M1, and separating the vermiculite, the mixture M1 and fumed silica with filter paper respectively to obtain a material to be filtered;

[0034] 2) mixing starch, hydrochloric acid and water to prepare a starch solution;

[0035] 3) The starch solution prepared in step 2) is mixed with the material to be filtered, and then filtered to obtain the algaecide base material.

[0036] In the above design, the material to be filtered is prepared by layering and superimposing vermiculite, Artemisia annua, calcium chloride, and fumed white carbon black, and the starch solution is mixed with the above-mentioned filter material to be filtered to obtain an algaecide base material. Then the algaecide base material is crystallized after being extracted with...

preparation example 1

[0059] 1) Pass vermiculite and Artemisia annua powder through a 100-mesh sieve. Put a 14cm-diameter plastic tray with holes (4-6 small holes with a diameter of 2mm can be manually drilled, and use cotton thread as drainage) plastic tray on a 2000mL beaker, put a 15cm qualitative filter paper on the tray to make the filter paper Embedded in a plastic tray, add 1.5g of vermiculite to the first layer of filter paper and use a brush to distribute it evenly on the filter paper; in the same way, add 15cm of filter paper to the first layer of filter paper, and then add 1.5g Artemisia annua powder and 1 g anhydrous CaCl 2 Powder and make it evenly distributed on the filter paper; cover the third layer of 15cm filter paper, add 0.4g fumed silica, and make it evenly distributed; finally, cover the fourth layer of filter paper;

[0060] 2) Weigh 0.1g of starch, add 10mL of 1% dilute HCl to dissolve, and make the volume to 250mL to obtain a starch solution;

[0061] 3) Add 25mL of starc...

preparation example 2

[0064] Prepare according to the preparation method of Preparation Example 1, the difference is that the consumption of the vermiculite is 1.6g, the consumption of the Artemisia annua powder is 1.6g, and the consumption of the fumed white carbon black is 0.3g, and the obtained Algae Base X2.

Abstract

The invention discloses a preparing method of an algicide base material, algicide and a preparing method and application of the algicide. The preparing method of the algicide base material includes the steps that 1, sweet wormwood herb and calcium chloride are mixed to prepare a mixture M1, and the mixture M1 and gaseous phase white carbon black are partitioned through filter paper to prepare a material to be filtered; 2, starch, hydrochloric acid and water are mixed to prepare a starch solution; the starch solution prepared in the step 2 and the material to be filtered are mixed and filtered to prepare the algicide base material. The preparing method of the algicide includes the steps that 1, the algicide base material prepared through the preparing method is extracted with ethyl acetate and then crystallized to prepare a crystal substance; 2, starch, hydrochloric acid and water are mixed to prepare a starch solution; 3, the crystal substance prepared in the step 1 and the starch solution prepared in the step 2 are mixed to prepare the algicide. By means of the design, the algicide has the advantages of being free of pollution, wide in material source, low in cost, convenient to use, high in algae removal efficiency and high in performance cost ratio.

Description

technical field [0001] The invention relates to the field of materials used for algae removal, in particular to a preparation method of an algae removal base material, an algae removal agent and a preparation method and application thereof. Background technique [0002] In recent years, my country and even the world are facing more and more serious problems of water eutrophication. Among them, China's lakes, reservoirs, rivers, and landscape water bodies are severely eutrophic, and cyanobacteria blooms occur frequently. [0003] At present, the main algae removal methods at home and abroad are: chemical method, physical method, biological method, physical and chemical method, etc. [0004] The chemical algae removal method has the advantages of less dosage, easy preparation and storage of chemicals, and good algae removal effect. It is currently the most used and most mature algae removal technology at home and abroad. Chemical algaecides include oxidizing algaecides and n...
