Abstract

The invention discloses a trace antibiotic efficient enrichment and separation method in a water environment. The adsorption performance of magnetic graphene on tetracycline antibiotics under different adsorption conditions is studied, and the change of the antibiotic concentration in solution before and after the adsorption is detected by an ultraviolet spectrophotometer, so that the corresponding adsorption rate of the antibiotics and the magnetic graphene adsorption capacity are calculated. The influence of different factors on the adsorption performance of the antibiotics is investigated; the optimum adsorption condition is obtained; the adsorption effect mechanism is analyzed; the adsorption kinetics and adsorption thermodynamics are discussed. According to the method, tetracycline hydrochloride TC is adopted as the research object, and the adsorption characteristics of MGO on the TC under different factors of the solution pH, temperature, dissolved organic matter (taking humic acid as an example) and the like are systemically studied, in particular to the adsorption kinetics and adsorption thermodynamics of the MGO on the TC.

Description

technical field [0001] The invention relates to a method for treating antibiotic wastewater, in particular to a method for efficiently enriching and separating trace antibiotics in a water environment. Background technique [0002] Tetracycline antibiotics are a kind of broad-spectrum antibiotics produced by Streptomyces, which are derivatives of polycyclic tetracenecarboxamide core. Tetracycline antibiotics can be divided into natural products and semi-synthetic products. Semi-synthetic products are also called second-generation tetracyclines, which bind to the 30S subunit of ribosomes and then prevent the combination of aminoacyl tRNA and ribosomes. resulting in pharmacological effects. [0003] Tetracycline antibiotics have both antibacterial and anti-inflammatory effects, so they are widely used at home and abroad, and are counted as one of the most widely used and widely used antibiotics. In 1928, Xia Fleming fortunately discovered penicillin. Until now, antibiotics h...
