Use of rice husk ash as a potent adsorbent of malachite green: kinetic and equilibrium studies

Autor: SIDJOU SIDJOU, Alexis, TCHAKOUNTE, Armand, TOME, Silvain, KEDE, Charles Melea, DIKA MANGA, Joseph

In this work, an adsorbent was prepared by calcination of rice husks and used as a membrane to remove malachite green contained in an aqueous solution. The synthesized adsorbent was characterized by X-ray diffraction (XRD), scanning electron microsco

Calcareous-support nanoscale Zero-valent iron: New findings on adsorption of Cr(VI) in aqueous solution

Autor: Tchakounte, Armand N., Poumve, Harlette Z., KEDE, Charles Melea, Dika, J.M.

This work focuses on Cr(VI) sorption by Calcareous and nZVI/Calcareous was investigated. The purpose of this study is to understand the mechanisms that govern the elimination of Cr (VI) and to find a suitable kinetics model of removal. Spectroscopic
