specific Embodiment approach 1
[0036] Specific embodiment one: this embodiment is a kind of method that utilizes iron-manganese dual-phase doped graphene to activate monopersulfate to remove endocrine disruptors in water, and it is completed according to the following steps:
[0037] 1. Mix monopersulfate with pretreated water: mix monopersulfate with pretreated water, then stir for 20min to 45min at room temperature and at a stirring speed of 160r / min to 250r / min to obtain A mixed solution of monopersulfate and pretreated water;
[0038] The monopersulfate described in step 1 is one of potassium monopersulfate, ammonium monopersulfate, sodium monopersulfate and calcium monopersulfate or a mixture of several thereof;
[0039] The concentration of endocrine disruptors in the pretreated water described in step 1 is 0.02 mg / L-100 mg / L;
[0040] The mass ratio of the quality of monopersulfate described in step 1 and the pretreated water is 1:(1000~10000);
[0041] 2. Adjust the pH value of the reaction: use 0...
specific Embodiment approach 2
[0067] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the endocrine disruptors described in step 1 are estrone, 17α-ethinyl estradiol, 17α-estradiol, 17β-estradiol, One or a mixture of estriol, diethylstilbestrol, nonylphenol, bisphenol A and octylphenol. Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0068] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the power of the ultrasonic oscillator described in Step 3 ① is 100W-1000W. Other steps are the same as those in Embodiment 1 or 2.
