Abstract
Antibiotic concentrations in wastewater generated by industries such as sewage treatment plants, medical pharmaceuticals and aquaculture has exceeded acceptable levels. It is particularly urgent to seek a method that can efficiently remove antibiotics. The removal potential of three quinolone antibiotics, pefloxacin (PF), levofloxacin (LF) and norfloxacin (NF), in simulated contaminated water was studied using a biochar-based nanomaterial prepared by a hydrothermal method. The data were fitted with adsorption kinetics, isotherms and thermodynamics. The results showed that ZnS–MoS2 activated biochar (ZMMBC) acheived maximum adsorption amounts of 199.42, 125.00 and 142.58 mg g–1 for PF, LF and NF, suggesting that ZMMBC has excellent adsorption performance. The adsorption mechanisms of PF, LF and NF molecules on ZMMBC include complexation, pore filling, π–π interactions, electrostatic interactions and hydrogen bond interactions.
期刊介绍:
Australian Journal of Chemistry - an International Journal for Chemical Science publishes research papers from all fields of chemical science. Papers that are multidisciplinary or address new or emerging areas of chemistry are particularly encouraged. Thus, the scope is dynamic. It includes (but is not limited to) synthesis, structure, new materials, macromolecules and polymers, supramolecular chemistry, analytical and environmental chemistry, natural products, biological and medicinal chemistry, nanotechnology, and surface chemistry.
Australian Journal of Chemistry is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
