Abstract
The invention discloses a composite disinfectant consisting of sodium chlorite, citric acid and bentonite. The composite disinfectant has the characteristics that the releasing speed of chlorine dioxide is slow and the disinfecting effect is good, is good in stability, long in shelf life and convenient to use. The invention also discloses a soil disinfecting method which comprises the following steps: the sodium chlorite, the citric acid and the bentonite are mixed uniformly according to mass ratio and spayed on the surface of soil, and the spraying amount in each kilo of soil is 25g-35g.
Description
Technical field
The present invention relates to the sterilization field, be specifically related to a kind of soil composite disinfectant and method for using thereof.
Background technology
Because chlorine dioxide has absorption and penetrability preferably to bacterium and other cells of microorganisms wall, can destroy the cell wall of bacterium, and its permeability is changed; DNA spills, and the intracellular enzyme of ability oxidation, the destroy microorganisms enzyme system; Protein is synthetic in the controlling microbial; Make amino-acid oxidase decomposition in the protein, thereby cell growth inhibiting also finally causes its death, therefore is widely used in fields such as sterilizing and water purified treatment.Chlorine dioxide is usually used in soil is carried out sterilizing; Can effectively kill the pathogen in the soil; The outburst of control epidemic situation is particularly in plant, if irregularly to disinfecting soil; Will break out extensive epidemic situation because of the pathogenic soil contamination by micro, thereby bring enormous economic loss.
But because chlorine dioxide is volatile and character is active, therefore instability uses very inconvenience and Disinfection Effect very poor.In order to improve the stability of chlorine dioxide, slow down its rate of release, in soil disinfection, adopt absorbent-type chlorine dioxide or response type chlorine dioxide at present usually.The absorbent-type chlorine dioxide is in aqueous solution of chlorine dioxide, to add adsorbent and process, and this disinfectant production is simple, and is easy to use, but the adsorption rate of chlorine dioxide is low, and loss is big, and gas is overflowed easily, and the holding time is short.The response type chlorine dioxide is with sodium chlorite and activator mix together, adds other adjuvant again and processes, and activator is generally weak acid such as solid tartaric acid, citric acid, niter cake.This soil disinfectant reacts activator and sodium chlorite and discharges chlorine dioxide; But need sodium chlorite and activator separately be deposited; Mix in proportion again in the time of sterilization; Use still inconvenience, and because the reaction velocity of sodium chlorite and activator is uncontrollable, the chlorine dioxide rate of release causes comparatively fast sterilizing rate lower.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of easy to use, soil composite disinfectant that sterilizing rate is high is provided, and the method for using of this soil composite disinfectant.
Above-mentioned purpose of the present invention realizes through following technical scheme:
A kind of soil composite disinfectant, the quality proportioning of each component is: sodium chlorite: citric acid: bentonite=1: 2～4: 6～10.
Preferred ingredients quality proportioning of the present invention is: sodium chlorite: citric acid: bentonite=1: 3: 8.
The production method of soil composite disinfectant of the present invention is: take by weighing sodium chlorite, citric acid and bentonite by above-mentioned quality proportioning; Earlier bentonite is dried down at 105 ℃～130 ℃; Then sodium chlorite and bentonite are mixed in closed container; Mix in closed container with citric acid again, divide bag hermetic package promptly to get soil composite disinfectant of the present invention with barrier material mixed product at last.
The present invention further provides the method for using of this soil composite disinfectant: said soil composite disinfectant is sprayed on soil surface, and the sprinkling amount in every kilogram of soil is 25g～35g.
The present invention is activator with the solid citric acid, under the condition that has water to exist, can generate chlorine dioxide with the sodium chlorite reaction; Isomorphous replacement takes place in the bentonitic octahedral sheet makes the bentonite structure sheaf have negative electrical charge; The hydrone and the cation of respective numbers appearred in interlayer; Thereby bentonite can be expanded and shrink; Can be lentamente from environment adsorption moisture be that citric acid and sodium chlorite reaction provide water environment because bentonite has reduced the contact area of citric acid and sodium chlorite, so the rate of release of ability slowed down reaction speed and chlorine dioxide.
The invention has the beneficial effects as follows:
(1) sterilizing rate is high.The soil composite disinfectant of the present invention slowly moisture in the absorbed air reacts citric acid and sodium chlorite and discharges chlorine dioxide, and the rate of release of chlorine dioxide is slow when placing air, and sterilizing rate is high, and Disinfection Effect is good.
(2) easy to use.In confined conditions, citric acid and sodium chlorite reactivity are extremely low, and the storage of can putting together is unpacked and just can directly be used, and product stability is good, and shelf life is long.
Description of drawings
Fig. 1 is the stability test result curve figure of soil composite disinfectant of the present invention.
Fig. 2 is that citric acid and sodium chlorite are adding bentonite and do not adding chlorine dioxide rate of release comparative trial curve map under the bentonitic situation.
Embodiment:
Further specify the present invention below in conjunction with specific embodiment and accompanying drawing.
Embodiment 1
A kind of soil composite disinfectant, the quality proportioning of each component is: sodium chlorite: citric acid: bentonite=1: 3: 8.
Production method: take by weighing sodium chlorite, citric acid and bentonite by above-mentioned quality proportioning; Earlier bentonite is dried down at 105 ℃～130 ℃; Then sodium chlorite and bentonite are mixed in closed container; Mix in closed container with citric acid again, divide bag hermetic package promptly to get with barrier material mixed product at last.
The soil composite disinfectant of present embodiment is carried out stability test and chlorine dioxide rate of release comparative trial, and the result is respectively like Fig. 1, shown in Figure 2.
Can be found out that by Fig. 1 soil composite disinfectant of the present invention is in 20 days, the percent of loss of chlorine dioxide is 6%-8% at high temperature (37 ℃), and room temperature is 3%-4%, and the percent of loss in 20 days is all lower, and basicly stable after 20 days.
Can find out that by Fig. 2 soil composite disinfectant chlorine dioxide rate of release of the present invention is starkly lower than and does not add bentonitic citric acid and sodium chlorite.
Embodiment 2
