Description
Technical Field
The invention relates to the technical field of disinfection, in particular to a bromochlorohydantoin disinfectant for soil treatment and a preparation method thereof.
Background
Bromochlorohydantoin is a specific disinfection bactericide of a performance, is used for the disinfection of industrial water treatment and mineral spring bathing ponds, indoor and outdoor swimming pool disinfection only needs 1-2 ppm to reach the effect, still can be used to various water treatment, bathroom disinfection deodorization, disinfection bleaching and be used for flowers and seeds disinfection in agriculture, soil sterilization, the aquaculture, aspects such as fruit fresh-keeping, bromochlorohydantoin can constantly release active bromide ion and active chloride ion through dissolving, form hypobromous acid and hypochlorous acid, hypobromous acid and hypochlorous acid that generate have strong oxidizing property, reach the purpose of sterilization with the biological enzyme oxidation in the microorganism body,
the existing low-toxicity broad-spectrum bactericidal pesticide is generally a chemical preparation. The early effect is more obvious, and the later stage quantity is bigger and bigger, along with the accumulation of medicament, the harm easily appears in remaining medicament. However, as people pay more attention to environmental protection and food safety, the use of pesticides is more and more limited, so that the invention provides the bromine-chlorine hydantoin disinfectant for soil treatment and the preparation method thereof, wherein the disinfectant has high sterilization rate and decomposition rate, has no residue and does not influence the emergence of crops.
