| 摘 要： | 用六种自然土壤进行了吸附氟的试验研究,表明土壤吸附氟的能力与土壤中粘粒和Al_2O_3的含量呈正相关,与Fe_2O_3及pH值呈负相关。理化性质不同的土壤吸附氟的能力各不相同,基本规律是酸性土壤吸附氟的能力较强,而碱性土壤较弱。

| Abstract: | Adsorption of fluoride on six natural soils with different physical and chemical properties were studied and the data were fitted to the adsorption isotherm of Freundlich and Langmuir. The affinity of fluoride to the soils was found to be positively correlated to the contents of clay material and A12O3, and negatively correlated to the Fe2O3 content and pH value.Of six soils tested, the adsorption of fluoride on acidic soils was stronger then that on alkaline soils. |
