The Study of the Sr,Co and Cs Ions Adsorption Capability of Halloysite in Zunyi of Guizhou Province

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.
