In this study, the removal of Pb (II) and Cd (II) in aqueous solution by employing hydrous manganese dioxide (HMO) is investigated. The HMO synthesized was characterized by SEM, XRD, BET, FT-IR, and XPS. Simultaneously, the effect of Zeta potential (ZP), solution pH and contact time were discussed. The results reveal that at pH 5.0, 1-HMO (-51.7 mV...

In this work, sorption of U(VI) on aqueous solution of hydrous manganese dioxide (HMO) is studied, and the effects of various environmental factors such as contact time, pH, ionic strength, coexisting ions, and temperature on the sorption behavior of HMO towards radionuclide U(VI) are investigated through batch experiments. Results indicate that pH...

In the current study, a new hybrid adsorbent HMO-001 was fabricated by impregnating nanosized hydrous manganese dioxide (HMO) onto a porous polystyrene cation exchanger resin (D-001) for enhanced lead removal from aqueous media. D-001 was selected as a support material mainly because of the potential Donnan membrane effect exerted by the immobilize...
