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。
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 Sr^2＋ , Co^2＋ and Cs^2＋ ions increases with pH of solution; （2） the adsorption ratio of the halloysite for the Sr^2＋ , Co^2＋ and Cs^2＋ 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 Sr^2＋ , Co^2＋ and Cs^2＋ ions, with the same adsorbent, the adsorption capacity of unit quality increases and adsorption ratio decreases with the rise of initial concentration of Sr^2＋ , Co^2＋ and Cs^2＋ ; （4） the adsorption of the halloysite for the Sr, Co and Cs ions mainly belong to broken bond charge adsorption and molecule adsorption.
