A Biodegradable Magnetic Nanocomposite as a Superabsorbent for the Simultaneous Removal of Selected Fluoroquinolones from Environmental Water Matrices: Isotherm, Kinetics, Thermodynamic Studies and Cost Analysis.

The application of a magnetic mesoporous carbon/β-cyclodextrin-chitosan (MMPC/Cyc-Chit) nanocomposite for the adsorptive removal of danofloxacin (DANO), enrofloxacin (ENRO) and levofloxacin (LEVO) from aqueous and environmental samples is reported in this study. The morphology and surface characteristics of the magnetic nanocomposite were investigated by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) adsorption-desorption and Fourier transform infrared spectroscopy (FTIR). The N adsorption-desorption results revealed that the prepared nanocomposite was mesoporous and the BET surface area was 1435 m g.

Occurrence, quantification, and adsorptive removal of nodularin in seawater, wastewater and river water.

The presence of potent hepatotoxic cyanotoxins such as nodularin (NOD) in drinking water, groundwater, surface water, seawater and recreational waters presents a major risks to human and environmental health. Human exposure to cyanotoxins could lead to various health effects such as liver damage, jaundice, neurotoxicity and gastroenteritis. Therefore, it is critical to investigate their occurrence in environmental matrices.
