[0030] Preparation of a molecularly imprinted hybrid material of estrogenic endocrine disruptors by first loading Fe on the surface of graphene using a hydrothermal one-step method 3 o 4 Microspheres to obtain magnetic graphene, and then use the magnetic graphene as a carrier to synthesize a magnetic graphene-based molecularly imprinted nanomembrane on its surface using molecular imprinting technology, including the following steps:
[0031] 1) Synthesis of magnetic graphene by hydrothermal method
[0032] 1mmol FeCl 3 ·6H 2 O was dissolved in 40mL of ethylene glycol, and after ultrasonic stirring to obtain a yellow transparent solution, 100 mg of graphene oxide was added, ultrasonically dispersed and mixed uniformly, then 5 mmol of anhydrous sodium acetate was added, ultrasonically stirred for 30 minutes, and the uniformly mixed solution was transferred to stainless steel In the reaction kettle, put it in an oven for crystallization reaction at 200°C for 16 hours. After co...
