Abstract Composite gel spheres (SA-BC) were prepared by using sodium alginate (SA) as a carrier and adding peanut shell biochar, their preparation conditions optimized to evaluate effectiveness in removing the ofloxacin (OFX) from water. In addition, antibiotic contamination Chinese urban waters was investigated. The results showed that variety of pollution existed natural water bodies, among which SA-BC performed excellently OFX water, with removal rate 70.72%, maintained good adsorption performance after four cycles use. experiments demonstrated general applicability practical application potential dynamic adsorption, resistance ionic interference heavy metals fitting data process consistent Langmuir isothermal model pseudo-second-order kinetic model. Further analysis three main mechanisms SA-BC, namely, role surface functional groups, π – electron donor–acceptor (EDA) interactions, electrostatic attraction.

The manufacture, modification, and application of surface-functionalized Fe3O4 nanoparticles in the extraction isolation antibiotics are reviewed this paper. Scanning electron microscopy (SEM) transmission (TEM) can be used to characterize morphological features nanoparticles, while Fourier Transform Infrared Spectrometer (FTIR) X-ray diffractometry (XRD) determine crystalline shapes distinctive functional groups these particles. We gathered a lot data investigate effects experimental parameters like pH, adsorbent dosage, contact time, ionic strength on from magnetic nanoparticles. additionally talked about mechanism action for separated how they utilized practical detection methods. This work concluded with an overview potential environmental friendliness dispersion functionalized as well challenges directions.
