Eco-FRIENDLY DISINFECTANT AND INSECTICIDE COMPOSITION WITH HYDROGEN PEROXIDE AND SODIUM CITRATE AND DISINFECTANT AND INSECTICIDE METHOD THEREOF

The present invention relates to an eco-friendly sterilization and insecticidal method using hydrogen peroxide and sodium citrate, and to an eco-friendly disinfectant and insecticide composition harmless to the human body, including hydrogen peroxide, sodium citrate and copper sulfate, and an eco-friendly sterilization and insecticidal method using the same.

In order to maintain the agricultural production system, it is necessary to remove pests and pests, and the use of chemical pesticides is a problem because it causes many side effects. The new strategy of pesticides should have a lower environmental impact than current chemical pesticides and should not harm the health of farmers or users. This environmentally friendly approach should be formulated based on environmental and ecological aspects.

Conventional insecticides such as Smithion and Parathion were manufactured using silver bromide or copper sulfate as the main ingredients of the insecticide, but these are highly toxic substances that destroy the ecosystem by killing harmful insects that parasitize plants as well as insects and amphibians beneficial to humans. It is devastation and further harms human beings, so there is an urgent need to manufacture eco-friendly disinfectants and insecticides.

In addition, some are methods of killing harmful insects using biological insecticides, which are natural enemies of harmful insects, using viruses, bacteria, fungi, predators, parasites, pheromones, and the like. Biological insecticides are capable of killing harmful insects after they reproduce and cause pests in plants, but have a disadvantage in that they do not increase the immunity of plants, which is necessary to prevent the occurrence of harmful insects or to prevent recurrence after treatment. And biopesticides are living organisms and require great care to maintain their activity.

In the entire specification, when a part “includes” a certain element, it means that other elements may be further included, rather than excluding other elements, unless otherwise stated.

Hereinafter, with reference to the accompanying drawings, embodiments of the present invention will be described in detail so that those of ordinary skill in the art can easily carry out the present invention. However, the present invention may be embodied in several different forms and is not limited to the embodiments described herein.

Specific details including the problem to be solved for the present invention, the means for solving the problem, and the effect of the invention are included in the embodiments and drawings to be described below. Advantages and features of the present invention, and a method for achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The present invention eco-friendly disinfectant and pesticide using hydrogen peroxide and sodium citrate, copper sulfate (CuSO ₄ ) and sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) After preparing a first solution by adding water, hydrogen peroxide (H ₂ O ₂ ) A second solution mixed with the first solution is prepared and sprayed on pests.

Figure 2 is a disinfectant and insecticide prepared according to an embodiment of the present invention, Figure 3 is a result of confirming the pH of the prepared disinfectant and insecticide was confirmed to be neutral or weakly acidic . If necessary, any one or more of sodium phosphate triphosphate (Na ₃ (PO ₄ ) ₂ ), potassium phosphate, zinc sulfate (ZnSO ₄ ), calcium phosphate, citric acid, and baking soda is further added The pH can be adjusted by mixing. When it becomes weak acid, neutral or weak alkali, eco-friendly disinfectant and insecticide can be manufactured. In particular, when prepared with weak alkali, it can be used for soil modification such as neutralization by mixing with soil later.

The disinfectant and insecticide are the copper sulfate (CuSO ₄ ) 2 parts by weight, hydrogen peroxide (H ₂ O ₂ ) 7 parts by weight and 400 to 500 parts by weight of water based on 1 part by weight of the sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) It is preferable to mix the parts. If necessary, the sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) Based on 1 part by weight of the tribasic sodium phosphate (Na ₃ (PO ₄ ) ₂ ), potassium phosphate, zinc sulfate (ZnSO ₄ ) , calcium phosphate (calcium phosphate), citric acid, and any one or more of baking soda may be mixed by 1 part by weight, respectively.

In the case of mixing only hydrogen peroxide (H ₂ O ₂ ) without mixing the sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) in the disinfectant and pesticide composition, the reaction is terminated within 1 hour during insecticide, so the sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) is mixed together, and the oxygen generation time is continuously maintained slowly so that the reaction continues for more than 8 hours . When the copper sulfate (CuSO ₄ ) and hydrogen peroxide solution (H ₂ O ₂ ) are first mixed, the reaction proceeds immediately, so the hydrogen peroxide solution (H ₂ O ₂ ) is preferably prepared as a second solution.

When the copper sulfate (CuSO ₄ ) in the disinfectant and insecticide composition is mixed in excess than the above conditions, the prepared disinfectant and insecticide are harmful to the human body, and there is a problem that an eco-friendly remover must be additionally mixed. Preferably, the first solution is prepared separately and then the copper sulfate (CuSO ₄ ) is mixed before spraying and insecticide is preferably performed.

The fungicides and insecticides prepared by the present invention can be insecticides within 10 to 20 minutes after spraying, and there is no odor generated from the disinfectants and insecticides in general, and there is an effect of removing odors together. In addition, in the case of a closed farmland such as a house, spraying a disinfectant and insecticide is very harmful to the human body, so an environment-friendly disinfectant and insecticide are required.

As shown in FIG. 1 , an environmentally friendly insecticidal method using hydrogen peroxide and sodium citrate according to a preferred embodiment of the present invention is performed by the following steps.

In the first step (S10), the hydrogen peroxide solution (H ₂ O ₂ ) reduces the copper sulfate (CuSO ₄ ) and promotes oxidation of the pests to thereby kill the pests.

First, the copper sulfate (CuSO ₄ ) and sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) were mixed and the water was added to prepare a first solution, and then the hydrogen peroxide solution (H ₂ O ₂ ) was added to the first The second solution mixed with the solution is sprayed to kill pests, but the hydrogen peroxide solution (H ₂ O ₂ ) reduces the copper sulfate (CuSO ₄ ) and promotes oxidation of the pests to kill.

The sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) is weakly alkaline, and in the reaction of the hydrogen peroxide solution (H ₂ O ₂ ) and copper sulfate (CuSO ₄ ), the acidity is made weakly acidic or neutral, and environmental pollution and odor removal It works.

If necessary, a small amount of zinc may be additionally mixed to eliminate some species of pests.

More specifically, in the first step (S10), the hydrogen peroxide solution (H ₂ O ₂ ) is oxidized by the reaction of [Formula 1] or [Formula 2] below.

[Formula 1]

H ₂ O ₂ + 2H ⁺ + 2e ^- = 2H ₂ O

[Formula 2]

H ₂ O ₂ + 2e ^- = 2OH ^-

The copper sulfate (CuSO ₄ ) according to an embodiment of the present invention is obtained by dissolving a metal dual reducing agent (additive-trisodium citrate, etc.) capable of reducing copper ions in water, and then reducing copper ions do.

The hydrogen peroxide solution (H ₂ O ₂ ) is reduced as shown in [Formula 1] in acid, and reduced as shown in [Formula 2] in neutral or alkali.

[Formula 1] or [Formula 2] can occur very quickly on the copper (Cu) surface, as a result, the electrical potential (Electrical Potential) of the copper surface becomes very high. The potential of the copper surface increased by the hydrogen peroxide (H ₂ O ₂ ) reduction reaction exhibits sterilization properties by promoting oxidation of living organisms in contact with the copper surface.

Therefore, it is possible to remove the fungus by causing a reduction reaction with hydrogen peroxide, which acts as an oxidizing agent.

Next, the second step (S20) is a reduction reaction of the hydrogen peroxide solution (H ₂ O ₂ ) and the sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) and the hydroxide ions generated by the reaction of water to kill the pests do.

More specifically, in the second step (S20), the hydrogen peroxide solution (H ₂ O ₂ ) may perform a sterilization function by the hydroxide ions (OH ⁻ ) generated by the following [Formula 3].

[Formula 3]

H ₂ O ₂ + 2e ^- = 2OH ^-

In addition, the sodium citrate (C ₆ H ₉ Na ₃ O ₉ ), as shown in the following [Formula 4], citrate (C ₆ H ₉ O ₉ ^3- ) is a hydroxide ion (OH ^- ) The sterilization function can be performed by

[Formula 4]

C ₆ H ₉ O ₉ ^3- + 3H ₂ O = C ₆ H ₁₂ O ₉ + 3OH ^- .

If necessary, in the second step (S20), tri-sodium phosphate (Na ₃ (PO ₄ ) ₂ ), potassium phosphate, zinc sulfate (ZnSO ₄ ), calcium phosphate, citric acid and baking soda Any one or more of them may be further mixed to increase the sterilization effect.

As such, the disinfectant and insecticide prepared using hydrogen peroxide (H ₂ O ₂ ), sodium citrate (C ₆ H ₉ Na ₃ O ₉ ) and copper sulfate (CuSO ₄ ) according to an embodiment of the present invention is the [Formula 1] to [Formula 4], by generating hydroxide ions (OH ⁻ ), it is possible to kill pests, and in this process, even odors can be simultaneously removed.
