Embodiment 1

[0045] 1. Mix persulfate with an aqueous solution containing carbamazepine, a typical antiepileptic drug: Mix monopersulfate with an aqueous solution containing carbamazepine, place it on a water bath shaker, the temperature is 25°C, and the number of oscillations is 60 / min~ 180 / min, shaking time 10min ~ 30min, you can get a mixed solution containing monopersulfate and carbamazepine;

[0046] The monopersulfate described in step 1 is one of potassium monopersulfate, ammonium monopersulfate, sodium monopersulfate and calcium monopersulfate or a mixture of several thereof;

[0047] The concentration of the carbamazepine aqueous solution described in step 1 is 0.1mg / L~100mg / L;

[0048] The quality of monopersulfate described in step 1 and the mass ratio of pretreatment waste water are 1:(1000~10000);

[0049] 2. Adjust the pH of the reaction: use 0.1mol / L~100mol / L HNO under the condition of shaking frequency 60 / min~180 / min 3 Or the NaOH of 0.1mol / L~100mol / L adjusts the pH value...

Embodiment 2

[0064] Embodiment 2: the difference between this embodiment and embodiment 1 is: in step one, the concentration of carbamazepine aqueous solution is 10mg / L~100mg / L, and other steps are the same as embodiment 1;

Embodiment 3

[0065] Embodiment 3: the difference between this embodiment and embodiment 1 is: in step one, the mass ratio of the quality of monopersulfate and the pretreatment waste water is 1: (5000~10000), and other steps are identical with embodiment 1;

Abstract

The invention relates to the field of water treatment, and discloses a method for treating an antiepileptic drug in water by utilizing MnxCo3-xO4 nanocages for activating monoperoxysulfate; the method particularly includes the following steps: one, mixing monoperoxysulfate with an antiepileptic drug-containing aqueous solution; two, adjusting a reaction pH; three, preparing the MnxCo3-xO4 nanocages; four, adding the MnxCo3-xO4 nanocages; five, recycling the MnxCo3-xO4 nanocages, and thus completing the method for treating the antiepileptic drug in the water by utilizing the MnxCo3-xO4 nanocages for activating monoperoxysulfate. The removal effect of the typical antiepileptic drug carbamazepine in water by using the method is obvious, the removal rate reaches 95%-99%, a catalytic material can be recovered and reused through centrifugation and separation, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a x co 3-x o 4 Nanocage activation of antiepileptic drugs in monopersulfate-treated water. Background technique [0002] With the advancement of science and technology and the improvement of detection technology, in recent years, a large number of pharmaceuticals and personal care products (PPCPs) have been detected in many water sources and wastewater treatment plants. Originated from people's daily life and medical and industrial production wastewater, it has strong biological activity and slow biodegradation, and will cause persistent harm to human health. Among them, carbamazepine (CBZ), which is used to treat epilepsy, bipolar disorder, bipolar mood disorder and acute mania, is widely used because of its remarkable drug effect. According to the survey, the per capita annual consumption of carbamazepine is about 15g, and it can even reach 50-150g in developed coun...
