In this work, static equilibrium experiments were conducted to distinguish the adsorption
performance between the two valence states of chromium on biochar derived from municipal …

Magnetic biochar was usually prepared using ferrous and ferric compounds as precursor of
magnetic medium. Ferrate, which could be an internal oxidative modifier, was less explored …

Dyes are well known for their hazardous impacts on public health and the environment. Dye
removal using monolithic adsorbents is an attractive approach for industrial applications and …

Nitrogen-doped carbon spheres (CSs-N) were synthesized by a hydrothermal method with
glucose as the carbon source and urea as the nitrogen source. The synthesized nitrogen …

In the present study, the potential of synthesized hydroxyapatite microfibrillated cellulose
(CHA/MFC) composite to remove chromium (VI) from aqueous solutions was investigated by …

In the present work, powdered activated carbon was derived from Peganum harmala seed
(PPAC) and then coated by green ZnO nanoparticles and finally applied for Cr (VI) removal …
