AbstractThe occurrence of fluoroquinolone antibiotics in wastewater has drawn great attention. Adsorption of widely used fluoroquinolone antibiotics ( enrofloxacin and ofloxacin) in wastewater using bamboo biochar was investigated. More than 99% of fluoroquinolone antibiotics were removed from the synthetic wastewater through adsorption. Adsorption capacities of bamboo biochar slightly changed when pH increased from 3.0 to 10.0. The adsorption capacity of bamboo biochar increased sharply when the initial concentration of enrofloxacin or ofloxacin increased from 1 to 200 mg L- 1 and then began to plateau with further increases in initial concentration. The maximum adsorption capacity ( 45.88 +/- 0.90 mg . g- 1) was observed when the ratio of bamboo biochar to fluoroquinolone antibiotics was 10. The enrofloxacin adsorption capacity of bamboo biochar decreased from 19.91 +/- 0.21 mg . g- 1 to 14.30 +/- 0.51 mg g- 1 while that of ofloxacin decreased from 19.82 +/- 0.22 mg g- 1 to 13.31 +/- 0.56 mg g- 1 when the NaCl concentrations increased from 0 to 30 g L- 1. The adsorptions of fluoroquinolone on bamboo biochar have isotherms that obeyed the Freundlich model ( r2 values were in the range of 0.990- 0.991).
