主 题：Adsorption Ciprofloxacin g-MoS2 nanosheets Biochar Soil remediation
摘 要：The g-MoS2 coated biochar(g-MoS2-BC)composites were synthesized by coating original biochar with g-MoS2 nanosheets at 300℃(BC300)/700℃(BC700).The adsorption properties of the g-MoS2-BC composites for ciprofloxacin(CIP)were investigated with an aim to exploit its high efficiency toward soil *** specific surface area and the pore structures of biochar coated g-MoS2 nanosheets were significantly *** g-MoS2-BC composites provided more n electrons,which was favorable in enhancing the n-n electron donor-acceptor(EDA)interactions between CIP and *** a result,the g-MoS2-BC composites showed faster adsorption rate and greater adsorption capacity for CIP than the original *** coated g-MoS2 nanosheets contributed more to CIP adsorption on the g-MoS2-BC composites due to their greater CIP adsorption capacity than the original ***,the synergistic effect was observed for CIP adsorption on g-MoS2-BC700,and suppression effect on *** addition,the adsorption of CIP onto g-MoS2-BC composites also exhibited strong dependence on the solution pH,since it can affect both the adsorbent surface charge and the speciation of *** was reasonably suggested that the mechanisms of CIP adsoiption on g-MoS2-BC composites involved pore-filling effects,k-k EDA interaction,electrostatic interaction,and ion exchange *** results are useful for the modification of biochar in exploiting the novel amendment for contaminated soils.
