preparation example Construction

[0037] The present invention also provides a method for preparing an algaecide, wherein the method comprises mixing HCl, starch, expanded vermiculite and water, and relative to 100 parts by weight of the expanded vermiculite, the amount of HCl used is 7-13 parts by weight, the amount of expanded vermiculite is 7-13 parts by weight, and the particle size of the starch is less than 100 μm.

[0038] In the preparation method of the algaecide, preferably, with respect to 100 parts by weight of the expanded vermiculite, the amount of HCl is 9-11 parts by weight, and the amount of starch is 9-11 parts by weight.

[0039] In the preparation method of the algaecide, preferably, the particle size of the expanded vermiculite is less than 75 μm.

[0040] According to a preferred embodiment of the preparation method of the algaecide of the present invention, such as figure 2 As shown, the process of mixing HCl, starch, expanded vermiculite and water includes the following steps:

[004...

Embodiment 1

[0050] 10 ml of a hydrochloric acid solution with a concentration of 1 wt % was uniformly mixed with 100 mg of wheat starch, and then the volume was adjusted to 100 ml with water to obtain a mixed solution.

[0051] The expanded vermiculite is crushed and sieved to obtain expanded vermiculite with a particle size of less than 75 μm. 1 g of expanded vermiculite with a particle size of less than 75 μm is added to the above mixed solution, and after stirring until uniformly mixed, the algaecide A1 of the present invention is obtained.

Embodiment 2

[0053] 10 ml of a hydrochloric acid solution with a concentration of 1 wt % was uniformly mixed with 100 mg of wheat starch, and then the volume was adjusted to 100 ml with water to obtain a mixed solution.

[0054] The expanded vermiculite is crushed and sieved to obtain expanded vermiculite with a particle size of less than 70 μm. 1.2 g of expanded vermiculite with a particle size of less than 70 μm was added to the above mixed solution, and after stirring until uniformly mixed, the algaecide A2 of the present invention was obtained.

Abstract

The invention discloses an algaecide, and a preparation method and application thereof. The algaecide comprises HCl, starch, expanded vermiculite and water, and based on 100 parts by weight of expanded vermiculite, the content of HCl is 7-13 parts by weight, the content of expanded vermiculite is 7-13 parts by weight, and the particle size of expanded vermiculite is less than 100 mu m. The preparation method of the algaecide comprises: mixing HCl, starch, expanded vermiculite and water, wherein based on 100 parts by weight of expanded vermiculite, the content of HCl is 7-13 parts by weight, the content of expanded vermiculite is 7-13 parts by weight, and the particle size of expanded vermiculite is less than 100 mu m. The algaecide provided by the invention has a removal rate on harmful algae of up to 99.89%.

Description

technical field [0001] The present invention relates to an algaecide based on modified vermiculite, a method for preparing the algaecide, and the application of the algaecide. Background technique [0002] With the intensification of water eutrophication, the algae pollution in the water body is becoming more and more serious. Therefore, the removal of algae in the water body is a hot topic today. The main algae removal methods in the prior art include chemical algae removal methods, physical methods, biological algae control methods, and physical and chemical methods. [0003] Chemical algae removal methods include direct chemical killing method and flocculation precipitation method. Among them, chemical algae removal is generally achieved by inhibiting the physiological function of algal cells, destroying the structure of algal cells, inactivating or even disintegrating algal cells, so as to achieve killing. Purpose of algae. When using inorganic algaecide to remove alga...
