Abstract
The invention discloses a photolytic type antidote for pesticide residues on fruits and vegetables, which belongs to the field of agricultural chemistry, adopts nano titanium dioxide as a photocatalytic oxidant to prepare dosage forms such as powder, wettable powder, water dispersible granules, suspending agents, hypertonic preparations and the like, and is sprayed before or after the fruits and vegetables are picked, so that the pesticide residues on the fruits and vegetables can be catalytically oxidized under sunlight or artificial illumination, and the antidote has the effects of sterilization and disinfection.
Description
Affiliated technical field
The invention belongs to agrochemical field, be specifically related to photodissociation type garden stuff pesticide residue antidote.
Background technology
Along with the raising of economic development and living standards of the people, people attract great attention to food security.The residues of pesticides of vegetable and fruit are serious food security hidden danger, because of the vegetable and fruit residues of pesticides cause the report of poisoning by food, common all spaces in a newspaper.The solution of this problem, first will ban use of high poison and persistent pesticide, and second will provide low toxicity and less-persistent pesticide to the peasant.It is impossible allowing the peasant not use agricultural chemicals fully, because the peasant will guarantee the output and the benefit of vegetable and fruit plantation, must use the pesticide control disease and pest.The 3rd, also to help the peasant effectively to reduce persticide residue on the vegetable and fruit.Even, originally remained in the agricultural chemicals in soil, water body, air and the fertilizer, still can be enriched in the plant, and transfer to the edible position that the mankind gather by plant absorbing because do not use high poison and persistent pesticide; And so-called low toxicity and less-persistent pesticide, neither be definitely nontoxic, take in the vegetable and fruit of these residues of pesticides for a long time, also can work the mischief to health.For addressing this problem, Agricultural University Of Nanjing has developed the microorganism formulation of can degrade soil and crop residues of pesticides.But after microorganism formulation was used, action time was slower, and needed to select corresponding microorganism formulation for use according to the remains of pesticide kind.Shanghai also has company to release a kind of fruits and vegetables detoxicating liquid, and it consists of various nutriments, and nutrients mass-energy has the ability of much degrading pesticide residues, still difficult at present judgement.
Summary of the invention
The objective of the invention is to: a kind of photodissociation type garden stuff pesticide residue antidote is provided, and this antidote is quick, wide spectrum, efficient, guarantees the fruits and vegetables edible safety conscientiously.
Technical solution of the present invention is: this antidote adopts nano titanium oxide as the photochemical catalytic oxidation agent, makes pulvis, wettable powder, water dispersible granules, suspending agent and hypertonic preparation.
Antidote of the present invention is with low cost, and is easy to use, and effect is remarkable.
The specific embodiment
The present invention adopts photochemical catalyst--and nano titanium oxide is a primary raw material, makes photodissociation type garden stuff pesticide residue antidote.Nano titanium oxide has good photocatalysis performance, and it absorbs luminous energy, excites to produce free electron and hole, and free electron and oxygen reaction generate O
2, the reaction of hole and water and oxygen produces HO, and the two all has a strong oxidizing property, and up to 502kJ/mol, and organic various bond energys such as agricultural chemicals are many about 400kJ/mol, can be degraded by the HO complete oxidation such as the energy of HO.
For improving the photocatalysis performance of titanium dioxide, except that being made into nano material, also can taking its surface light sensitization, carry out means such as metal ion mixing, semiconductor coupling, heavy metal deposition, chelated surface, make high efficiency photocatalyst thus.
When this antidote is used for water treatment,, need with carrier such as appendix such as hollow glass micro-ball or glass fibre fabric for preventing that titanium dioxide powder is floating, can not evenly distributing and recycle.
Antidote of the present invention, adopt nano titanium oxide or be raw material with its high efficiency photocatalyst of making, can add or not add auxiliary agents such as dispersant, wetting agent, bleeding agent, with the conventional method of pesticide producing, make formulations such as pulvis, wettable powder, water dispersible granules, suspending agent, hypertonic preparation.
When the present invention uses, do not add water (pulvis) or add water (other formulation), before gathering 1-2 days or gather after, be sprayed onto on the vegetable and fruit, carry out illumination, can bring into play photo-catalysis function with sunlight or artificial light source, residues of pesticides on the oxidative degradation vegetable and fruit, and non-secondary pollution.
The present invention also has the sterilizing effect in degrading pesticide residues, Yu Caiqian uses can alleviate disease, can prolong the fresh-keeping storage time in adopting the back use.
The present invention not only can use for the peasant, also can use for purchase, processing and the marketing unit of vegetable and fruit.
