Description

A kind of compound prescription fruits and vegetables agricultural chemicals falls residual dose
Technical field
The present invention relates to a kind of compound prescription fruits and vegetables agricultural chemicals and fall residual dose, for the fruits and vegetables in family, garden stuff processing enterprise and farmland, booth, fall residual processing, belong to the chemical degradation agent technical field of remains of pesticide.
Background technology
Pesticide species is a lot, and conventional agricultural chemicals has kind more than 300.Vegetables are in planting process, and because pesticide dosage is too much or it is too short apart from spraying time interval to pluck, its surface has the noxious materials such as a large amount of agricultural chemicals and metabolin remaining.These noxious materials are difficult for being washed off by clear water.The long-term edible fruit and vegetable that has pollution by pesticides, can cause harmful toxic matter gathering in human body, to health, brings potential threat.How effectively to remove agricultural chemicals residual in fruits and vegetables and become the major issue that people are concerned about.At present, pesticide residual degradation technology comprises mechanical degradation method (illumination, irradiation, ultrasonic wave etc.), microbial degradation method and chemical degradation method.In the residual method of numerous removal agricultures, chemical method is the most portable effective method wherein, and the chemistry widely adopting to fall residual dose be mainly oxidant, as ozone, Peracetic acid, hydrogen peroxide, hypochlorite etc.
The kind of agricultural chemicals and structure are extremely complicated, and the environment in field is also comparatively complicated during actual using, and conventionally uses Multiple Pesticides to use together.In addition, the dissolubility of agricultural chemicals, volatility, adsorptivity also can directly affect its residual form in environment around, therefore the oxidation of single chemical oxidizing agent except residual effect fruit very imprecise, especially for agricultural chemicals and the metabolin thereof of the labyrinth of those hard degradations, the effect of chemical oxidizing agent just is more difficult to prove effective.
Summary of the invention
The development of the high-efficiency broad spectrum pesticide residual degradation agent of applicable Multiple Pesticides is still the important topic of current fruit-vegetable food safety.For the problems referred to above, the object of this invention is to provide a kind of multicomponent compound prescription fruits and vegetables agricultural chemicals and fall residual dose, described agricultural chemicals falls residual dose and consists of A composition and B composition,
Described A composition comprises: SODIUM PERCARBONATE, alkaline conditioner and anion surfactant;
Described B composition comprises: iron powder, acid regulator and anion surfactant.
In A composition, contain oxidant SODIUM PERCARBONATE and alkaline conditioner, can play to the residues of pesticides of fruit and vegetable surfaces the effect of oxidation and hydrolysis.Most of agricultural chemicals hydrolysis under alkaline environment is stronger, therefore in said composition, adds alkaline conditioner with enhanced hydrolysis, but does not affect the oxidation of oxidant SODIUM PERCARBONATE.
In B composition, contain iron powder, have the dual-use function of reducing agent and catalyst, under sour environment, reduction and catalytic action can be strengthened.For the part pesticide species that is difficult for oxidized dose of removal, can be decomposed by catalytic reduction effect.
Thereby the anion surfactant all containing in A, B two compositions can remove fat-soluble or water miscible remains of pesticide to be dissolved in the water from fruit and vegetable surfaces, further removes the remains of pesticide of fruit and vegetable surfaces.
Preferably, described alkaline conditioner is NaOH or potassium hydroxide;
Preferably, described acid regulator is any one in niter cake, oxalic acid, citric acid, tartaric acid;
Preferably, described anion surfactant is any one in lauryl sodium sulfate, ammonium lauryl sulfate, dodecyl alcohol ether sodium sulfate, dodecyl alcohol ether ammonium sulfate.
Further, A composition, in weight ratio, comprising: SODIUM PERCARBONATE 0.1-0.5 part, alkaline conditioner 5-50 part, anion surfactant 0.01-0.1 part;
B composition, in weight ratio, comprising: iron powder 1-10 part, acid regulator 1-10 part, anion surfactant 0.01-0.1 part.
Another object of the present invention is to provide the compound method that the fruits and vegetables that comprise A, B two compositions fall residual dose, and it is specially two kinds:
One method is mixed with solution: A composition is dissolved in and in the aqueous solution, forms A mixed solution by described weight ratio, B composition is dissolved in and in the aqueous solution, forms B mixed solution by described weight ratio.
Preferably, in described A mixed solution: SODIUM PERCARBONATE 100-500mg/L, alkaline conditioner 5-50g/L, anion surfactant 0.01-0.1g/L; In described B mixed solution: iron powder 1-10g/L, acid regulator 1-10g/L, surfactant 0.01-0.1g/L.
Another kind is to be made into pulvis or tablet: A composition, by weight mixing, is made to pulvis or is pressed into tablet, form A pulvis or A tablet, B composition, by weight mixing, is made to pulvis or is pressed into tablet, form B pulvis or B tablet.
The using method of residual dose falls in above-mentioned fruits and vegetables agricultural chemicals:
For the fruits and vegetables agricultural chemicals of solution state, fall residual dose, adopt respectively A, two kinds of mixed solutions of B to soak successively fruits and vegetables 30min.
For the fruits and vegetables agricultural chemicals of pulvis or tablet, fall residual dose, according to concentration requirement, A, two kinds of pulvis of B are added to the water respectively and form A solution and B solution or A, two kinds of tablets of B are added to the water respectively and form A solution and B solution, then A, two kinds of solution of B are soaked to fruits and vegetables 30min successively.
Preferably, in described A solution: SODIUM PERCARBONATE 100-500mg/L, alkaline conditioner 5-50g/L, anion surfactant 0.01-0.1g/L; In described B solution: iron powder 1-10g/L, acid regulator 1-10g/L, surfactant 0.01-0.1g/L.
The compound prescription fruits and vegetables agricultural chemicals that comprises A, B two compositions in the present invention falls in residual dose, contain oxidant SODIUM PERCARBONATE, reducing agent iron powder and pH adjusting agent as bronsted lowry acids and bases bronsted lowry, when these components contact with remains of pesticide, under the synergy and strengthening of the multiple effects such as oxidation, reduction, catalysis, can make the Multiple Pesticides that kind is different with structure fully degrade, thereby realize the effect that reduces residues of pesticides and detoxification.
During use, first add A composition, agricultural chemicals is oxidized and is hydrolyzed, then add B composition, agricultural chemicals is carried out to catalytic reduction degraded.By use, contain A and B two compositions aqueous solution fruit and vegetable surfaces after treatment, its surperficial various pesticides removal rates can reach more than 90%, and effect is remarkable.
