| 摘 要： | 对贵州遵义埃洛石吸附Sr、Co、Cs的性能进行了实验研究,结果表明:(1)埃洛石对Sr2 、Cs2 、Co2 的吸附能力随着pH值增大而增大;(2)埃洛石对Sr2 、Cs2 、Co2 的吸附随着液固比的增大,吸附率逐渐增大,单位质量吸附量明显减小;(3)埃洛石对Sr2 、Cs2 、Co2 的吸附过程中,当吸附剂量相同时,其单位质量吸附量随初始浓度的升高而增加,吸附率则随初始浓度的升高而减小;(4)埃洛石对Sr2 、Cs2 、Co2 的吸附主要靠断键产生的可变负电荷和分子吸附。

| Abstract: | The Sr,Co and Cs ions adsorption capability of the halloysite in Zunyi of Guizhou Province were studied.The results show that:(1) the adsorption capability of the halloysite for the Sr2 ,Co2 and Cs2 ions increases with pH of solution;(2) the adsorption ratio of the halloysite for the Sr2 ,Co2 and Cs2 ions increases and adsorption capability of unit quality decreases with the increase of liquid-solid ratio;(3) in the process of the adsorption of the halloysite for the Sr2 ,Co2 and Cs2 ions,with the same adsorbent,the adsorption capacity of unit quality increases and adsorption ratio decreases with the rise of initial concentration of Sr2 ,Co2 and Cs2 ;(4) the adsorption of the halloysite for the Sr,Co and Cs ions mainly belong to broken bond charge adsorption and molecule adsorption. |
