摘　　要：通过在反应釜中直接添加丙酮制备原位改性丙酮水热炭(XM-AC),并以水热炭(XM)为参照,探究XM-AC对水中盐酸四环素(TCH)的吸附性能。结果表明,相比XM,XM-AC具有较高的比表面积、孔容积和芳香性,准二级动力学和Langmuir更适合描述XM-AC对TCH的吸附过程,表明该吸附过程主要是受两种以上因素共同影响的单分子层吸附。pH值对XM-AC吸附TCH的影响较大。XM-AC对TCH的吸附作用主要为离子交换和π-π电子供体受体相互作用。In situ modified acetone hydrothermal carbon(XM-AC)was prepared by adding acetone directly in the reaction kettle,and the adsorption performance and mechanism of XM-AC for tetracycline hydrochloride(TCH)in water were investigated with the reference of hydrothermal carbon(XM).The results show that XM-AC has higher specific surface area,pore volume and aromaticity than XM,and the pseudo second order kinetic equation and Langmuir model are more suitable to describe the adsorption process of TCH on XM-AC,indicating that the adsorption process is mainly affected by two or more factors.The pH value has great influence on the adsorption of TCH by XM-AC.The adsorption of TCH on XM-AC is mainly ion exchange and adsorptionπ-πElectron donor receptor interaction.
