| 摘 要： | 以多溴联苯醚典型单体2，2′，4，4′?四溴联苯醚（BDE?47）为研究对象，阐明了其在土壤矿物质与有机质上的吸附解吸行为及特征。结果表明：土壤中无机矿物质对BDE?47的吸附贡献不大，而有机质是调控BDE?47在土壤中吸附行为的关键组分；有机质对BDE?47的吸附能力与其有机碳含量和物理化学特性相关；BDE?47在腐殖酸上的解吸存在显著的滞后现象。

| Abstract: | In this study,we used 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) as a model compound to elucidate the sorption-desorption behavior and characteristics of PBDEs in soil minerals and organic matter. The experimental results indicated that: inorganic minerals in soil sorb little BDE-47,while organic matter is the key component that regulate the sorption behavior of BDE-47 in soil; the sorption capacity of organic matter sorb BDE-47 is related to its organic carbon content and physical-chemical properties; desorption of BDE-47 from humic acids exhibits significant hysteresis. |

| Keywords: | BDE-47 soil sorption desorption hysteresis |
