The studied bamboo based activated carbon (BbAC) with high specific surface area (SSA) and high micro pore
volume was prepared from bamboo scraps by the combined activation of H3PO4 and K2CO3. The BbACwas characterized
based on the N2 adsorption isothermat 77 K. The results showed that the SSA and pore volume of BbAC
increased with increasing impregnation ratio and reached maxima at the impregnation ratio of 3:1 at 750 °C.
Under these optimal conditions, the BbAC obtained could have a maximum SSA of 2237 m2/g and a maximum
total pore volume of 1.23 cm3/g with the micro pore ratio of more than 90%. The adsorption performance of ciprofloxacin
(CIP) on the BbAC was determined at 298 K. The Langmuir and Freundlich models were employed to
describe the adsorption equilibrium and the kinetic data were fitted by pseudo first-order and pseudo secondorder
kinetic models. The results showed that the Langmuir model and the pseudo second-order kinetic model
presented better fittings for the adsorption equilibriumand kinetics data, respectively. Themaximumadsorption
amount of CIP (613mg/g) on the BbACwas much higher than the report in the literature. Conclusively, the BbAC
could be a promising adsorption material for CIP removal from water
