Abstract
The invention relates to a degradation method for pesticide residues. The method comprises the following steps of: (1) diluting a degradant for the pesticide residues by 20 times; (2) after a pesticide is sprayed for 24 hours, spraying the diluted degradant to the surfaces of crops 1 to 2 days before the crops are harvested; and (3) exposing under sunlight or an artificial light source for at least 10 hours. By the method, the pesticide residues can be reduced by over 70 percent effectively, the pesticide residues on the surfaces of agricultural products can be degraded, and the pesticide residues inside the agricultural products can also be reduced.
Description
Technical field
The present invention relates to a kind of Methods of Degrading Pesticide Residues.
Background technology
Pesticide residue refer to because pesticides application remains in the agricultural chemicals parent in organism, agricultural-food and environment and has the general name of impurity, meta-bolites and the reaction of toxicology meaning.China is that big country is produced and used to world pesticide.A large amount of pesticide residue can cause acute toxicity.Remains of pesticide also can, at people's body accumulation, can cause some diseases over after a certain amount of, as cardiovascular disorder, diabetes, hepatopathy, cancer etc.; Agricultural chemicals also accumulating in human body can be passed to the next generation by pregnant and lactation, brings disaster to descendants's health.Bread is the staff of life, and food is with An Weixian.When foodstuffs industry has developed into the large industry of the first in the world, food safety is also subject to extensive concern.Therefore, the pesticide residue of reduction agricultural-food are trends of the times.Product in the market belongs to types of detergents mostly, real degrading pesticide, and can cause the secondary pollution to water quality.
Summary of the invention
The object of this invention is to provide a kind of Methods of Degrading Pesticide Residues, can effectively reduce pesticide residue more than 70%, and the pesticide residue of the surface of agricultural products of can degrading, the pesticide residue of agricultural-food inside can be reduced again.
Degradating agent for residual agricultural chemicals of the present invention is comprised of the component of following weight percent:
Wherein nano titanium oxide has good photocatalysis performance, and it can absorb luminous energy, and the material that generation has strong oxidizing property carrys out the chemical bond in degrading pesticide.Persulphate can be Sodium Persulfate, Potassium Persulphate or ammonium persulphate, is strong oxidizing property material.Selenium in potassium selenite can enter rapidly vegetable cell in photosynthesis, adds the foreign substance removing function of cell, accelerates the aging of pesticide molecule chain and fracture simultaneously, greatly reduces the pesticide residue in farm crop.
The preparation method of above-mentioned degradation agents, comprises the following steps:
(1) 0.5-1.5% nano titanium oxide, 30-60% persulphate, 0.3-1.3% potassium selenite and appropriate pure water are mixed, constantly stir until all components dissolves completely;
(2) continuing to add pure water to make total weight percent is 100%, stirs.
Methods of Degrading Pesticide Residues of the present invention comprises the following steps:
(1) adopt the degradating agent for residual agricultural chemicals being formed by following weight percent component:
(2) by 20 times of described degradation agents dilutions;
(3) after pesticide spraying, reach 24 hours, before the 1-2 before farm crop are gathered days, the degradation agents of dilution is sprayed to crop surface;
(4) under sunlight or source of artificial light, expose at least 10 hours.
