摘　　要：本文主要研究了辽西某膨润土的性质及其开发的产品钠化膨润土、活性白土、白炭黑在不同搅拌时间下的除氟试验,通过试验得出搅拌时间对各种除氟剂的除氟效果影响基本相同,都在2h左右达到吸附平衡;各产品的除氟效果依次为白炭黑>活性白土>原矿>钠基土,并从机理上分析了该试验结果。This paper mainly studied the properties of bentonite in Western Liaoning and removing fluorine experiments of its productions that are sodium addition bentonite, activated clay, white carbon under different stirring time. Through the experiment we obtained that the effort of stimng time on different fluorine-removal agent are almost same, reaching adsorption equilibrium in 2 hours. The defluormation effect of each product was in sequence of carbon-white 〉activated clay〉raw ore〉sodium clay. And the experimental results were also analyzed by mechamsm.
