摘要

Abstract

In this work

Fe/Ni nanoparticles were produced through Fe(Ⅱ) and Ni(Ⅱ) reduction by NaBH

and they were stabilized by a kind of prepared granular adsorbent (Fe/Ni@PGA). Fe/Ni@PGA as an environment-friendly activator was used to activate persulfate (PS) for the removal of ciprofloxacin from aqueous solution. Fe/Ni@PGA was systematically characterized via Brunauer-Emmett-Teller (BET) method

X-ray diffraction (XRD)

scanning electron microscopy (SEM)

and Fourier transform infrared spectroscopy (FTIR). The effects of PS concentration

initial solution pH

Fe/Ni@PGA dosage

initial ciprofloxacin concentration

reaction temperature

anions

and natural organic matters on the removal of ciprofloxacin by Fe/Ni@PGA/PS were analyzed. The removal efficiency of ciprofloxacin by Fe/Ni@PGA/PS was 93.24% under an initial pH of 3.0

PS concentration of 10 mM

Fe/Ni@PGA dosage of 0.1 g

and reaction temperature of 30 ℃. Fe/Ni@PGA could still exhibit high catalytic activity after nine cycles of regeneration. The removal mechanisms for ciprofloxacin by the Fe/Ni@PGA/PS system were proposed. In summary

the Fe/Ni@PGA/PS system could be

applied as a promising technology for ciprofloxacin removal.
