Molecular engram polymer of pyrethroid-like pesticide and application thereof

[0032] Example 1: Preparation of a molecularly imprinted polymer with cypermethrin as a template.

[0033] Weigh 1.0 mmol of the template molecule cypermethrin and add it into a glass test tube filled with 10 mL of toluene, and then add 6.0 mmol of α-methacrylic acid (MAA). The above reaction solution was placed in a high-power ultrasonic cleaner for ultrasonic treatment for 1 hour so that the cypermethrin pesticide molecule was fully combined with α-methacrylic acid, and then 30mmol of ethylene glycol dimethacrylate (EDMGA) was added as a crosslinking agent and 65mg of azobisisobutyronitrile (AIBN), then ultrasonic treatment for 10 minutes, and nitrogen gas (N 2 ) deoxygenated for 15 minutes, and finally vacuum-sealed. After the sealed glass test tube was placed in a 55° C. water bath thermostat to react for 48 hours, a block-shaped cypermethrin molecularly imprinted polymer was obtained. The molecularly imprinted polymer is ground and pulverized and passed through a 100-me...

[0035] Example 2: Preparation of a molecularly imprinted polymer with bifenthrin as a template.

[0036] Weigh 1.0 mmol of the template molecule bifenthrin and add it into a glass test tube filled with 10 mL of toluene, and then add 6.0 mmol of α-methacrylic acid (MAA). The above reaction solution was placed in a high-power ultrasonic cleaner for ultrasonic treatment for 1 hour, so that the bifenthrin pesticide molecules could fully interact with α-methacrylic acid, and then add 30 mmol of ethylene glycol dimethacrylate (EDMGA) to Combined agent and 65mg azobisisobutyronitrile (AIBN), then ultrasonic treatment for 10 minutes, and nitrogen gas (N 2 ) deoxygenated for 15 minutes, and finally vacuum-sealed. After the sealed glass test tube was placed in a 55°C water bath thermostat for 48 hours of reaction, a block-shaped bifenthrin molecularly imprinted polymer was obtained. The molecularly imprinted polymer is ground and pulverized and passed through a 100-mesh sieve and a 20...

[0038] Example 3: Preparation of a molecularly imprinted polymer with phenthrin as a template.

[0039] Weigh 1.0 mmol of the template molecule phenothrin and add it into a glass test tube filled with 10 mL of toluene, and then add 6.0 mmol of α-methacrylic acid (MAA). The above-mentioned reaction solution was placed in a high-power ultrasonic cleaner for ultrasonic treatment for 1 hour, so that the phenothrin pesticide molecule was fully combined with α-methacrylic acid, and then 30 mmol of ethylene glycol dimethacrylate (EDMGA) was added for the cross-linking process. Combined agent and 65mg azobisisobutyronitrile (AIBN), then ultrasonic treatment for 10 minutes, and nitrogen gas (N 2 ) deoxygenated for 15 minutes, and finally vacuum-sealed. After the sealed glass test tube was placed in a 55°C water-bath thermostat for 48 hours of reaction, a block-shaped molecularly imprinted polymer of phenthrin could be obtained. The molecularly imprinted polymer is ground and pulveriz...
