Description

We prepared the SiO2 encapsulated zeolite for the high efficient removal of heavy metals with low concentrations in water. The outer layer SiO2 enhanced the adsorption performance of heavy metals, and the removal efficiencies of five heavy metals (Pd, Cd, Zn, Cu and Mn) can be more than 97%. The SiO2 encapsulated zeolite can be repeatly used for the removal of heavy metals. More importantly, the cations transfer from solution via SiO2 layer to inner layer of zeolite was found, which is very important to understand the transport behaviors of heavy metals.
