TL;DR: This is the first study of Cr( VI) removal from aqueous solution using this hybrid nanocomposite at near-neutral pH and the thermodynamics study reveals that Cr(VI) adsorption on ZnO-GO is spontaneous, endothermic, and entropy-driven.

Sustainable removal of Cr(VI) using graphene oxide-zinc oxide nanohybrid: Adsorption kinetics, isotherms and thermodynamics
TL;DR: In this article , decorated zinc oxide (ZnO) nanoparticles (NPs) on graphene oxide nanoparticles were synthesized via the solvothermal process, and the surface deposition of ZnO-GO was characterized through Fourie Transform Infra-red (FTIR), UV-Visible, X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive Spectroscopy (EDS), and Brunauer-Emmett-Teller (BET) techniques.

Comparison of Cr(VI) adsorption and photocatalytic reduction efficiency using leonardite powder.
TL;DR: In this paper , leonardite powder was used in both adsorption and photocatalytic treatment systems by only pulverizing without any chemical treatment, achieving a complete removal efficiency (100%) for 3 g/L of adsorbent dose with an initial Cr(VI) concentration of 10 mg/L at pH 2 for 2 h.

Physico-chemical treatment techniques for wastewater laden with heavy metals
TL;DR: In this article, the technical applicability of various physico-chemical treatments for the removal of heavy metals such as Cd(II), Cr(III, Cr(VI), Cu(II, Ni(II) and Zn(II).

A review of chemical, electrochemical and biological methods for aqueous Cr(VI) reduction
TL;DR: This review describes the environmental implications of Cr(VI) presence in aqueous solutions, the chemical species that could be present and then the technologies available to efficiently reduce hexavalent chromium.

Chromium in drinking water: sources, metabolism, and cancer risks.
TL;DR: Bioavailability results and kinetic considerations suggest that 10–20% of ingested low-dose Cr(VI) escapes human gastric inactivation, and the incompleteness of gastric detoxification argue against a threshold in low- dose extrapolation of cancer risk for ingested Cr( VI).
