| 摘 要： | 采用振荡平衡法分别对莠灭净在不同甘蔗种植区土壤中的吸附特性进行了比较研究。结果表明,莠灭净在四地土壤中的吸附等温曲线符合Freundlich方程,广西来宾、广西扶绥、广西武鸣蔗土对莠灭净的吸附等温线呈S型,安徽萧县蔗土吸附等温线呈L型,吸附常数分别为4.85,4.00,2.87,0.77。莠灭净难以被土壤吸附,吸附能力与土壤有机质质量分数呈正相关。四地土壤对莠灭净吸附能力依次为广西来宾、广西扶绥、广西武鸣、安徽萧县。

| Abstract: | In order to evaluate the environment safety of ametryn,the adsorption behavior of ametryn in four kinds of soil were studied by the batch equilibrium method.The results showed that ametryn was difficult to be adsorbed by soil,the adsorption isotherm curve in soils was described by the Freundlich model.The adsorption isotherms in Anhui Xiaoxian belonged to L-type,the others belonged to S-type,the adsorption constants (Kd) of Guangxi Laibin,Guangxi Fusui,Guangxi Wuming,Anhui Xiaoxian were 4.85,4.00,2.87,0.77,respectively.Adsorption of ametryn was primarily related to the organic content in soil.The adsorbabilities of ametryn in soils followed the order of Guangxi Laibin,Guangxi Fusui,Guangxi Wuming,Anhui Xiaoxian. |
