The study of the Sr、Co、Cs oions adsorption capability of halloysite at the Beichuan of Sichuan province

The Sr、Co、Cs oions adsorption capability of the halloysite at the Beichuan of Sichuan Province are studied.The results show that:① the Sr、Co、Cs oions adsorption capability of the halloysite increases with pH of solution;② the Sr、Co、Cs oions adsorption ratio of the halloysite increases and adsorption capability decreases with adsorbent;③the adsorption capability of the halloysite to Sr、Co、Cs oions increases and adsorption ratio decreases with initial concentration of Sr²⁺、Co²⁺、Cs²⁺;④ the adsorption of the halloysite to Sr、Co、Cs oions are mainly belong to broken bond charge adsorption and molecule adsorption.
