Adsorption behavior of levofloxacin hydrochloride on non‐degradable microplastics aging with H2O2
Abstract
Plastics pollutants, especially microplastics (MPs, PET (0.995 mg/g), H2O2‐PS (1.057 mg/g) > PS (0.957 mg/g), H2O2‐PVC (1.107 mg/g) > PVC (0.975 mg/g). After H2O2 aging, the hydrogen bond (‐OH) was more obvious, and π‐π interactions were significantly enhanced. These non‐degradable MPs mainly adsorbed Lev‐HCl by micropore filling (contributions: PVC 65.9%, PS 56%, PET 63.5%). The current study highlights the potential of non‐degradable MPs to act as a vector for Lev‐HCl in the aquatic environment, especially after H2O2 aging.
