| 摘 要： | 借助灰色关联度筛选出复合污染体系Cd2+/AT,Cu2 +/AT中沉积物和生物膜吸附阿特拉津(AT)的主要吸附位,包括活性组分铁氧化物(Fe)、锰氧化物(Mn)、有机质(OMs)及其交互作用,并建立主要吸附位与AT吸附量的多元线性回归模型.多元线性回归模型结果表明:Cd2+对AT的吸附表现为协同作用,Cd2+质量浓度为0.2mg·L-1时协同效应最显著；Cu2对AT的吸附表现为拮抗作用,抑制效应随Cu2+质量浓度增大呈逐渐增强趋势.Cd2+,Cu2+显著影响了活性组分及其交互作用对AT的吸附行为,活性组分之间的交互作用在AT迁移转化方面发挥着至关重要的作用.

| Abstract: | The main sites of atrazine(AT) adsorption onto the surficial sediments and natural surficial coating samples in Cd2+/AT,Cu2+/AT composite contamination systems were filtrated according to gray correlation of the active fractions of Fe oxides,Mn oxides,organic materials and their interactions.A multiple regression model between AT adsorption amount and main adsorption sites was established.The results show that Cd2+ expresses synergetic effect on AT adsorption with the most significant efficiency at Cd2+ level of 0.2 mg·L-1.The antagonistic effect caused by Cu2+ on AT adsorption is generally enhanced by the increasing of Cu2+ levels.Cd2+ or Cu2+ can dramatically influence active fractions and their interactions on AT adsorption.The interactions among active fractions play an important role in controlling the environmental behaviors of AT in aquatic environments. |
