摘要
对苏州高岭土、北川埃洛石、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高岭土类粘土矿物对Sr2+、Co2+、Cs2+的吸附能力随着pH值增大而增强,在碱性条件下对Sr2+、Co2+、Cs2+的吸附能力随碱性程度的增加而快速增大;②高岭土类粘土矿物对Sr2+、Co2+、Cs2++的吸附随着吸附剂量的增大,吸附率逐渐增大,单位质量吸附量明显减小;③母液浓度增大,单位质量吸附量增加,吸附率减小;④贵州埃洛石、北川埃洛石对Sr2+、Co2+、Cs2+的吸附性能相近,埃洛石对Sr2+、Co2+、Cs2+的吸附能力好于苏州高岭土。
The Sr, Co, Cs ions adsorption capability of the halloysite at the Zunyi of Guizhou Province,Beichuan of Sichuan Province and the kaolin at the Suzhou of Jiangsu Province are studied.The results show that： （1） the Sr, Co, Cs ions adsorption capability of the halloysite and kaolin increases with pH of solution; （2） the Sr, Co, Cs ions adsorption ratio of the halloysite and kaolin increases and adsorption capability decreases with adsorbent; （3） the adsorption capability of the halloysite and kaolin to Sr, Co, Cs ions increases and adsorption ratio decreases with initial concentration of Sr^2＋, Co^2＋. Cs^2＋; （4） the adsorption capability of the halloysite to Sr, Co, Cs ions are better than that of kaolin.
