Embodiment 1

[0031] Mix 21 parts of ionic liquid [BPy]Cl with a mass fraction of 14% and 69 parts of Na2CO3 with a mass fraction of 24% to obtain a two-phase infiltration system, and then add 10 parts with a mass fraction of 42% HMT-PAM-Gel to obtain Gel-like mixture, the above-mentioned gel-like mixture was burned at 120° C. for two hours, and then stored in a vacuum oven at 40° C. for 48 hours to prepare the adsorption material.

[0032] Take out the adsorption material and use it to capture pyrimethanil in the fungicide. The specific capture process is to configure the pyrimethanil fungicide and the adsorption material at a mass ratio of 2:1, place it at 27°C for 15 minutes, and record the target before and after capture. The permeability is shown in Table 1.

Embodiment 2

[0034] The preparation method of this example is the same as that of Example 1, the only difference is that the type of ionic liquid in the preparation process is different. In this example, the ionic liquid is changed to [2-aemim][PF6](1-aminoethyl-3- Methylimidazole hexafluorophosphate), and the rest of the conditions were unchanged, and the permeability of the target before and after capture was recorded in Table 1.

Embodiment 3

[0036] The preparation method of this example is the same as Example 1, the only difference is that the type of ionic liquid in the preparation process is different, in this example, the ionic liquid is changed to [bmim][PF6](1-acetoxy-3-methylimidazole hexafluorophosphate), and the rest of the conditions were unchanged, and the permeability of the target before and after capture was recorded in Table 1.

[0037] It can be seen from the above examples and Table 1 that the permeability of pyrimethanil used to separate the fungicides is 99.2%, 74.3%, and 59.3% respectively after changing the composition of the ionic liquid in the adsorption material, so [BPy] When Cl was used as an ionic liquid, the penetration rate of pyrimethanil in the fungicide was the largest, and the penetration effect was the best.

[0038] Depend on figure 1 , 2 It can be seen from and 3 that when the ionic liquid in the adsorption material is [BPy]Cl, a round structure can be formed, but changing the ...

Abstract

The invention discloses a bactericide pyrimethanil adsorption material and a preparation method and application thereof. The method includes: mixing N-buthylpyridine chlorine salt, sodium carbonate and polyacrylamide-hexamethylenetetramine grafted chelated gel, and burning at a temperature of 120 DEG C to obtain the adsorption material, wherein a mass ratio of N-buthylpyridine chlorine salt to sodium carbonate to polyacrylamide-hexamethylenetetramine grafted chelated gel is 2:6:2. The preparation method of the adsorption material is quick and convenient; by adoption of the special ionic liquid, salt and grafted chelated gel in preparation, the prepared adsorption material is high in targeting performance and collection efficiency. By adoption of the method, the recovery rate of pyrimethanil in bactericide reaches 99.2%, wide linear range, low detection limit and low relative standard deviation are realized, and the national requirement on detection of pyrimethanil in bactericide can bemet.

Description

technical field [0001] The invention belongs to the field of environmental science and engineering, and in particular relates to a pyrimethanil adsorption material in a fungicide, a preparation method and an application thereof. Background technique [0002] Pyrimethanil is a new type of fungicide, belonging to anilinopyrimidines. It is currently the fungicide with the highest activity in the control of Botrytis cinerea. Its unique mechanism of action prevents the infection of bacteria and kills them by inhibiting the production of bacteria-infected enzymes. The mechanism of action is unique, and it is effective against Botrytis cinerea that has developed resistance to commonly used non-anilinopyrimidine (benzimidazoles and carbamates) fungicides. At the same time, it has the function of systemic conduction and fumigation. After spraying, it quickly reaches the parts of the plant such as flowers and young fruits that cannot be reached by spraying to kill germs, and the dru...
