Synthesis of core–shell structured magnetic mesoporous silica microspheres with accessible carboxyl functionalized surfaces and radially oriented large mesopores as adsorbents for the removal of heavy metal ions

Abstract

Core–shell structured mesoporous silica with accessible carboxyl functionalized surfaces and radial oriented large mesopores was fabricated as a recyclable adsorbent for the adsorption of Cd(<sc>ii</sc>), Cu(<sc>ii</sc>), and Pb(<sc>ii</sc>).
