中文摘要：

通过对滇池泥炭土和周围表层土壤两种土样及由其分离出的胡敏酸（HA）、胡敏素（HM）对诺氟沙星（NOR）的吸附特征展开研究．有机元素分析结果显示，滇池周边泥炭土含有非常丰富的碳资源．NOR在土壤及其组分中表现了显著的非线性吸附特征．相对于原始土壤和HM，HA组分对NOR表现了较强的吸附作用；而且，泥炭土与表层土相比，有机碳含量较高的泥炭土对NOR的吸附也相对较高；但是无机矿物对NOR的表观吸附有显著的贡献，因此应该避免用有机碳含量对吸附系数进行标准化．随着对HA的逐级萃取，NOR在HA上吸附的非均质性越来越强．

英文摘要：

numic lake area. investigated acid （HA） and humin （HM） were separated from one peat soil and one surface soil in Dianchi The sorption characteristics of ~ The organic elemental analysis carbon. NOR showed significantly nonlinear norfloxacin （NOR） in the original soil, HA and HM were showed that the peat soil from Dianchi was very rich in organic sorption characteristics in the soil and its components. Compared with original soils and HM, HA fractions displayed strong sorption to NOR. Moreover, the peat soil showed higher sorpfion to NOR relative to the surface soil due to its high organic carbon contents. The apparent sorption contributed by inorganic minerals may be important for NOR, and thus the normalization of sorption coefficients using organic carbon content should be avoided. The extraction of HAs from the surface soil fractionated HAs. The sorption nonlinearity increased with the extraction, suggesting that HA heterogeneity for NOR sorption increased with the extraction.
