Fabrication of manganese dioxide/carbon/attapulgite composites derived from spent bleaching earth for adsorption of Pb(<scp>ii</scp>) and Brilliant green

Abstract

Manganese dioxide/carbon/attapulgite ternary composites were fabricated<italic>via</italic>hydrothermal method of the SBE served as adsorbents for the efficient removal of Pb(<sc>ii</sc>) and BG.
