摘要:
以采自现代黄河三角洲地区不同特性的土壤为研究对象,研究了滴滴涕(DDTs)在土壤中的吸附行为及土壤各特性参数对吸附行为的影响。实验结果表明:DDTs在该地区土壤中的吸附为弱非线性吸附,符合Langmuir吸附等温方程,分配作用占主导地位;影响DDTs的吸附量的主要因素为土壤中有机质含量,其对Langmuir方程中最大吸附量的影响程度可用本文构建的定量方程描述;DDTs的吸附量与土壤的粘粒含量呈正相关关系,与土壤pH值及土壤可溶解盐含量无明显相关。本研究为构建现代黄河三角洲地区土壤中持久有机污染物的归趋提供数据支持。
Abstract:
The adsorption behavior of DDTs in soil collected from modern Yellow River delta and the influence of characteristic parameters of soil on the adsorption are studied. The results show: (1) the adsorption isotherms could be described by Langmuir equation which is weakly non-linear and the distribution function is the main effect; (2) the main factor influencing the maximum adsorption quantity is the organic matter content of the soil and the degree can be described by the quantitative equation built in this paper; (3) a positive linear correlation is found between the soil adsorption quantities and the clay content of soil, while the relationship between pH, soil dissolvable salt and the soil adsorption quantity is not obvious. The results can be used in the calculation of the fate of POPs in the soil of Yellow River delta.
