Abstract

The invention discloses a method for degrading antibiotics by activating persulfate by using a Fe-N self-doped algae-based carbon catalyst, the Fe-N self-doped algae-based carbon catalyst is used as a catalyst for activating persulfate to degrade the antibiotics, and the Fe-N self-doped algae-based carbon catalyst is prepared by using anabaena as a raw material, soluble carbonate as a pore-forming agent, and the Fe-N self-doped algae-based carbon catalyst is prepared by using the Fe-N self-doped algae-based carbon catalyst as a catalyst for activating persulfate. And calcining under the condition that the temperature is greater than 600 DEG C to obtain the catalyst. According to the method disclosed by the invention, the Fe-N self-doped algae-based carbon catalyst with the advantages of large specific surface area, multiple reaction active sites, high catalytic activity and the like is taken as a catalyst, and the Fe-N self-doped algae-based carbon catalyst can effectively activate persulfate and convert the persulfate into active groups with strong oxidation effect on antibiotics, so that the active groups can be utilized to realize effective degradation of the antibiotics; the method has the advantages of being simple in process, convenient to operate, low in cost, good in degradation effect and the like, has a good degradation effect on various antibiotics, and is high in use value and good in application prospect.

Description

technical field [0001] The invention belongs to the technical field of material preparation and environmental catalysis, and relates to a method for using Fe-N self-doping algae-based carbon catalyst to activate persulfate to degrade antibiotics. Background technique [0002] As an effective bacteriostatic agent, antibiotics are widely used in human medical treatment and animal husbandry, but the rich application scenarios also provide various ways for the discharge of antibiotic-contaminated wastewater, increasing the risk of environmental exposure. Over the past few decades, antibiotic-contaminated wastewater has become increasingly polluted, and trace amounts of antibiotics can be detected in natural water bodies and even in drinking water, posing a major threat to aquatic organisms and human health. Due to its non-biodegradability, the traditional sewage treatment technology has limited effect on the treatment of antibiotic wastewater. Advanced oxidation technology base...
