A critical global issue in the 21st century is water shortage, as well as its pollution with
noxious metal ions and organic dyes. To extract these pollutants from wastewater, a variety …

Graphene with atomic layer of sp 2-hybridized carbon atoms in a hexagonal structure has
attracted multidisciplinary attention since its discovery. Due to the inherent advantages of …

Graphene oxide (GO) and its composites have attracted widespread attentions as novel
adsorbents for the adsorption of various heavy metal contaminants. Because of the unique …

In the present work, a cost-effective Indian jujube seeds derived activated carbon (IJSAC)
prepared via o-phosphoric acid chemical activation, is studied for the sequestration of …

Few-layered graphene oxide (FGO) was synthesized from graphite by using the modified
Hummers method, and was characterized by scanning electron microscopy, atomic force …

Graphene nanosheets (GNSs) that were obtained by vacuum-promoted low-temperature
exfoliation were used to adsorb lead ions from an aqueous system. The pristine and …

This work aims to verify the feasibility of utilizing iron ore tailing (IOT) in porous geopolymer
and intends to broaden the application of porous geopolymer in heavy metal removal …

The aim of this work was to synthesis highly amorphous geopolymer from waste coal fly ash,
to be used as an adsorbent for lead Pb (II) removal from aqueous wastewater. The effect of …

The adsorption of Ni (II) on oxidized multi-walled carbon nanotubes (MWCNTs) as a function
of contact time, pH and foreign ions in the absence and presence of polyacrylic acid (PAA) …

The disposal of about 8 million ton/year of eggshell waste produced worldwide is an
environmentally challenging issue. However, this waste can be converted to new materials …
