以泰乐菌素作为目标有机污染物，系统研究了不同来源的纳米黑炭与腐殖酸的复合物对泰乐菌素的吸附特性和机制。结果表明：黑炭与腐殖酸复合后其对泰乐菌素的吸附明显增强；吸附在24h可完全达到平衡，吸附动力学可以用二级动力学较好的拟合；且线性吸附模型和Freundlich吸附模型可以较好的拟合吸附等温线；黑炭与腐殖酸复合后其对泰乐菌素的吸附受溶液pH值和离子强度的影响。吸附机制主要以疏水性分配、氢键作用和离子交换为主。“,”Based on tylosin was wsed as one representative organic pollutant, the sorption characteristics and mechanism of tylosin on different sources of nano black carbon-humic acid complexes was invesitigated. Results showed that the sorption capacity of black carbon and humic acid complex was higher than that of black carbon and humic acid; the sorption equilibrium could be obttained within 24hours;the sorption kinetics of tylosin on both black carbon and black carbon-humic acid complex fitted the pseudo-second-order kinetics model;the sorption isotherms could fit well with the Henry model and Freundlich model;the sorption capacity of tylosin on black carbon and humic acid complex would be altered in different solution chemistries (i.e., pH and ionic strength of solutions). Ion-exchange, hydrogen-bond, and hydrophobic play a main role in the sorption of tylosin on black carbon and humic acid complex.
