Adsorption Behaviors of Norfloxacin by Soils Spiked Black Carbon

[Objective] The research aimed to study the effects of the soils spiked black carbon on the sorption behavior of norfloxacin.[Method] The black carbon was obtained by rape residue firing in open air.The effect of the black carbon on the sorption of soils to norfloxacin was studied using the batch equilibrium.[Result] The black carbon had large surface area using SEM,as well as including C,H and O elements using FT-IR.The equilibrium status was obtained within 6 hours when the ratio of adsorbent to solution was 1∶300.The adsorption isotherm was well fitted by Langmuir and Freundlich equations.[Conclusion] The sorption ability and capacity of soils were enhanced with the addition of black carbon.
