This study investigates the removal of ammonium from aqueous using zeolite synthesized
from red mud. The zeolite was characterized with X-ray diffraction (XRD), scanning electron …

In this study, the optimum ammonium removal by activation of synthetic zeolite in the
aqueous phase was investigated by batch ion exchange adsorption assay, and its surface …

The objectives of this study were to modify Chinese natural zeolite by NaCl and to
investigate its suitability as a low-cost clay adsorbent to remove ammonium from aqueous …

In this study, the porous material zeolite with cage-like structure was modified to prepare
silver-doped zeolite 4A (abbreviated as Ag@ 4A) using ion exchange method, with a silver …

In this study, the adsorption efficiency of Philippine natural zeolite for treating acid mine
drainage is investigated. The metal ions considered were Cu2+, Ni2+, and Pb2+ ions. The …

Zeolite A was synthesized from fumed silica and sodium aluminate precursors. The optimum
conditions for synthesis of zeolite A were studied to obtain a high ion-exchange capacity and …

The low-cost P zeolite was synthesized from coal fly ash of power plants through the
modified hydrothermal process, and further treated through the tombarthite La modification …

Zeolite Na-A from waste sludge of water treatment plants was synthesized via a
hydrothermal process for the purpose of ammonium removal. Sludge samples, with and …

Natural zeolite was modified by NaCl, AlCl3 and thermal treatment for the removal of NH4+
and PO4 3− ions. The characteristics of the modified zeolite (AlZ) and its mechanism for the …

The development of the process of sodium activation of zeolite has been an effective
technique for enhancing the efficiency of ammonium removal. In this research, the optimum …
