In recent years, poisoning incidents caused by eating vegetables and fruits in China have occurred, 98% of which are caused by pesticides such as organic phosphorus in vegetables and fruits.
Pesticides work by inhibiting cholinesterase in the central nervous system of insects, but they also inhibit cholinesterase in the human body, block nerve transmission, cause muscle paralysis, and cause poisoning.
Most of the pesticide residues are caused by the spraying of pesticides on raw materials.
China's vegetable and fruit farming industries are mostly extensive management. The pesticides used in the growth of fruits and vegetables are basically determined by the individual farmers. At the same time, due to the high price of low-residue pesticides in China, farmers are in the interest of controlling the pests and diseases of apple growth, and still use pesticides such as methamidophos and parathion.
The problem of pesticide residues seriously threatens the health of consumers and has attracted the attention of the national government departments. Especially after the accession to the WTO, the export of fruits, vegetables and their products in China has encountered trade technical barriers of Japan, the United States and the European Union due to the problem of pesticide residues. , causing great economic losses.
Chlorine dioxide is an internationally recognized new generation of safe, efficient and broad-spectrum disinfection, preservation and deodorant. Its effective chlorine is 2.6 times that of chlorine; it reacts with organic matter in water without generating trichloromethane (carcinogenic, teratogenic, mutagenic) substances, which are confirmed to be medical, food processing, fresh-keeping, drinking water and industrial recycling. The ideal agent for disinfection and deodorization in water, etc., is a green disinfectant and is listed as A1 grade safe fungicide by WHO.
Chlorine dioxide has a good degradation effect on methyl parathion and methamidophos.
At a certain temperature, using the same concentration of chlorine dioxide, the degradation of methamidophos is more obvious than the degradation of methyl parathion; at a certain temperature, for the determination of chlorine dioxide, with the reaction time The prolongation of chlorine dioxide enhances the degradation of methamidophos and methyl parathion.
Chlorine dioxide is one of the effective methods for controlling pesticide residues such as methamidophos and methyl parathion in the cleaning of vegetables and fruits. When using chlorine dioxide as a raw material for pesticide residues, select the appropriate concentration according to the type of pesticide and the concentration of pesticide residues. At the same time, the effects of factors such as residence time and temperature of circulating water should be considered.
[disinfection mechanism]
The stabilized chlorine dioxide releases free chlorine dioxide by activation, and the chlorine dioxide is unstable to release new ecological atomic oxygen:
ClO2——Cl- + 2[O] The new ecological atomic oxygen has a strong oxidizing effect. It oxidizes the amino acid in the protein by oxidizing the active group of the protoplasmic protein of the microorganism to achieve the purpose of killing germs and viruses. Its bactericidal ability is 2.5 times that of chlorine. Chlorine dioxide can also react with ammonia, sulfides, and organic substances in the air or on the surface of various substances to achieve the effect of removing odor.
