高氟土壤的氟动力学吸附试验研究

Experiment on Fluoride Kinetics Adsorption of High Fluoride Soils

通过室内水土试验,研究山东高密高氟地区的土壤对氟的动力学吸附特性,并用典型的低氟土试验进行对比。从化学动力学的角度讨论高氟土壤对氟的吸附行为。高氟土壤对氟的吸附有其特殊性;高氟土壤对氟的吸附分为快、慢两个阶段;羟基是影响氟吸附的重要因素。

Through indoor soil test, the article is based on strudies fluorine kinetics adsorption of soils in high density fluoride region of Shandong Province and comparing by low fluoride soil experiment. It discusses the way of Fluoride adsorption by high fluoride soils from the point of chemical kinetics. The results show that fluoride adsorption by high fluoride soils has its particularity ; the tendency of fluoride adsorption is faster at the first stage and slower at the second stage; Hydroxyl is one of the important factors to affect the fluoride adsorption.
