| 摘 要： | 为了明确二甲戊灵在土壤中的吸附性能,采用气相色谱技术,研究了二甲戊灵在草甸土和砂壤土中的吸附特性。结果表明,二甲戊灵可被土壤强烈吸附,吸附浓度与其在平衡溶液中的浓度呈良好的线性关系,吸附特性符合Freundlich方程,草甸黑土、砂壤土对二甲戊灵的吸附为物理吸附,吸附量均很高,吸附系数分别为67.16和41.16,且有机质含量高的草甸黑土吸附量大于有机质含量低的砂壤土。 |

| Abstract: | The gas choromatographic was used to study the absorption of pendimethalin in black soil and sand soil.The isotherm data fitted the Freundlich equation.The absorption coefficient of black soil and sand soil were 67.16 and 41.16.The absorptive capacity were much higher in two different soils.Absorption rates of pendimethalin fitted the following order:black soil > sand soil.The results showed that the absorption of pendimethalin was higher in the high organic substance soil than that in the low organic substance soil and pendimethalin was absorbed consumingly by soil. |
| Keywords: | pendimethalin soil absorption |
