| 摘 要： | 本文对8种土壤进行了氟的淋溶试验研究,表明不同的土壤氟的淋溶程度各不相同,氟的淋溶浓度的变化曲线也不一致。在此基础上分析了影响氟淋溶作用的因素,并讨论了淋溶出来的氟对人类健康的潜在威胁。

| Abstract: | Eight natural soils were used to study the leaching of fluoride. The result showed that the leaching degrees of fluoride in various soils were different, and the leaching curves of fluoride in soils were not the same. The average fluoride concentration in leaching liquid of soils was found to have positive correlation with the contents of soluble fluoride in soil and pH, and logarithmic negative correlation to the adsorption coeflients (K.t) of fluoride in soils. Of eight soils tesed, the leaching of fluoride in alkaline soils was stronger than that in acidic soils. The potential effect of fluoride leached from soils on the human being was also discu-ssed. |
