| 摘 要： | 本文在研究膨润土、累托石和沸石样品的矿物组成和基本物化性能的基础上,以这三种样品作为吸附剂,研究它们在静态条件下对Sr2+的吸附效果.结果表明:在静态吸附条件下,三种样品的吸附效果因物化性质的不同而有所差异,其中,膨润土的吸附效果要好于其他两种样品.三种样品对Sr2+的吸附率都随着原液浓度的增加而减小,随着吸附剂量的增加而增大.0.1g的膨润土、累托石和沸石样品的最大吸附量分别为19.71mg/g,11.83mg/g,12.27mg/g,对应于0.002mol/L,0.005mol/L,0.01mol/L的原液浓度获得.

| Abstract: | On the basis of analyzing the mineral composition and the basic physicochemical properties of bentonite,rectorite and zeolite sample,using the three sample as absorbent,studied their absorption capacity for Sr2+ in static condition.The results showed that the absorption capacity of the three sample were different with the difference among their physicochemical properties,absorp-tion capacity of bentonite was better than the other two in static absorption condition.Absorption rate of the three sample decreas... |
