摘要
采用平衡吸附法研究阿特拉津在2种三峡消落带土壤中的吸附行为,探讨pH值、离子强度等因素对阿特拉津吸附的影响。结果表明,在消落带土壤中,pH值和吸附量呈负相关,离子强度的增强和腐殖酸的添加有利于土壤对阿特拉津的吸附。
Equilibrium adsorption method is used to study the adsorption characteristics of atrazine by two soils in water-level-fluctuating zone of Three-Gorges.The effect caused by pH,ionic strength and addition of humic acid on adsorption of atrazine is discussed.The results show that pH is negatively correlated with adsorption.Ionic strength and addition of humic acid would contribute to adsorption of atrazine by soil samples.
