Problems solved by technology

[0004] However, most adsorbent materials are greatly affected by the pH of the water body, and can only exert excellent adsorption performance in a narrow pH range. However, the pH of the actual environmental water body has fluctuations, which affects the adsorption performance of the adsorption material.

[0053] Example 1 Application of bimetallic nitrogen-doped magnetic porous carbon material in adsorption CIP

[0054] 1. The application of nine kinds of bimetallic nitrogen-doped magnetic porous carbon materials in the adsorption of CIP

[0055] Take MNPC-600-0.4, MNPC-700-0.4, MNPC-800-0.4, MNPC-900-0.4, NPC-700-0, MNPC-700-0.2, MNPC-700-0.6, MNPC-700-0.8 and MNPC -700-1.0, under the same conditions (pH=7, temperature 25°C, initial concentration of CIP 40mg / L, volume of CIP solution 50mL, material dosage 0.04g / L), placed in a constant temperature shaker, oscillating at a speed of 180rpm After 24 hours, the solution was filtered through a 0.22 μm filter membrane, and the absorbance at 270 nm was measured with a UV spectrophotometer, and the adsorption capacity (1) was calculated, and the results were as follows Figure 8 In (a) and (b) shown. MNPC-700-0.4 has the highest adsorption capacity, with an adsorption capacity of 936.84mg / g.

Abstract

The invention relates to an application of a bimetal nitrogen-doped magnetic porous carbon material in adsorption of ciprofloxacin. The bimetal nitrogen-doped magnetic porous carbon material has ultrahigh adsorption capacity for ciprofloxacin, has excellent adaptability in relatively wide pH, ion strength and humic acid concentration ranges, has strong adaptability to natural water bodies, and canquickly remove ciprofloxacin in the water bodies.

Description

technical field [0001] The invention relates to the field of pollution control, in particular to the application of a bimetallic nitrogen-doped magnetic porous carbon material in removing ciprofloxacin. Background technique [0002] Ciprofloxacin (CIP), a synthetic antibiotic widely used to treat some bacterial infections in humans and animals, is also one of the antibiotics frequently detected in many rivers and has been recognized as one of the most important emerging pollutants. Trace residues of ciprofloxacin in water are toxic to some aquatic organisms and may lead to the development of antibiotic-resistant bacteria, ultimately leading to weakened drug efficacy and significantly increased human health risks. In addition, ciprofloxacin can inhibit the growth of bacteria and reduce the biodegradation efficiency of traditional sewage treatment plants. Therefore, it is particularly important to remove CIP from water bodies. [0003] To protect environmental water bodies a...
