Abstract
A sorbent device based on a porous membrane bag (e.g., porous propylene membrane bag) encapsulated alkaline-modified zeolite (e.g., alkaline-treated USY zeolite). A process for removing heavy metals, such as Cd(II), Cr(III), and Pb(II) from an aqueous solution or an industrial wastewater samples with the sorbent device is provided. A method for preparing the alkaline-modified zeolite is also described.
