| Popis: | Here, Calotropis gigantea fiber (CGF) was first treated using NaClO2 to chemically modify the fiber surface to improve its hydrophilicity. Subsequently, the resulting NaClO2-CGF was used as the biosorbent to remove three fluoroquinolone antibiotics including enrofloxacin (Enr), ciprofloxacin (Cip), and norfloxacin (Nor). The results demonstrate that NaClO2-CGF shows optimum adsorption properties at pH = 6, with the maximum adsorption capacity of 50–70 mg/g. Further, NaClO2-CGF can achieve its adsorption equilibrium within 30 min, an indication of its fast adsorption kinetics. After five adsorption-desorption cycles, a higher adsorption percentage is still observed, suggesting its good regeneration for use in successive cycles. |
