【 摘 要 】

ZSM-5 zeolite was successfully prepared through hydrothermal synthesis, for the first time, using natural clay collected from the potash ore deposit of a Salt Lake in Qaidam Basin, China. The resultant product was characterized by a series of technologies. The adsorption capacity of the final product for removing Pb (II) in aqueous solution was also investigated. The adsorption processes can be well described by the pseudo-second-order rate equation and classical Langmuir model. Results suggested that Salt Lake clay is a promising low-cost precursor for the industrial production of microporous aluminosilicate, and the ZSM-5 zeolite exhibited a potential application in Pb(II) pollution cleanup.
