The present study involves the adsorption of hexavalent Chromium (Cr (VI)) using chitosan
grafted graphene oxide (CS-GO) nanocomposite in batch mode. The CS-GO nanocomposite …

Biochar prepared from sludge and liriodendron leaves (SLAC) was modified by Fe 3+(SLAC-
Fe), and they were used to remove methyl orange (MO) from single system and aqueous …

Hexavalent chromium is a well-known highly toxic metal, considered a priority pollutant.
Industrial sources of Cr (VI) include leather tanning, cooling tower blowdown, plating …

The presence of hexavalent chromium in wastewater is a potential hazard to aquatic
animals and humans. There are various mechanisms proposed, kinetic models used and …

Wastewater and agricultural runoff contain phosphate and chromium ions, which are
common pollutants. In particular, industrial wastewater can contain excessive untreated …

2, 4-Dinitrophenylhydrazine (DNPH) immobilized on sodium dodecyl sulfate coated nano-
alumina was developed for the removal of metal cations Pb (II), Cd (II), Cr (III), Co (II), Ni (II) …

In this work, beta-cyclodextrin–chitosan modified walnut shell biochars (β-CCWB) were
synthesized as a low-cost adsorbent for the removal of heavy metal Cr (VI) from aqueous …

Discharge of phosphate into aquatic environment by various human activities such as
agricultural runoff, animal waste, sewage, industry and detergents, leads to the deterioration …
