Environmental remediation of heavy metal ions by novel-nanomaterials: A review

Environ Pollut. 2019 Mar:246:608-620. doi: 10.1016/j.envpol.2018.12.076. Epub 2018 Dec 26.

Abstract

Recently, novel-nanomaterials with excellent sorption capacities, mild stability, and environmental-friendly performance, have enabled massive developments in capturing heavy metal ions. This review firstly introduces the preparation and modification of novel-nanomaterials (e.g., MOFs, nZVI, MXenes, and g-C3N4). Then, the heavy metal ions' sorption properties and the impact of environmental conditions have been discussed. Subsequently, the sorption mechanisms are verified through batch experiments, spectral analysis, surface complexation models, and theoretical calculations. Finally, the applications prospects of novel-nanomaterials in removing heavy metal ion polluted water have also been discussed, which provide perspective for future in-depth research and practical applications.

Keywords: Heavy metal ions; Interaction mechanism; Nanomaterials; Sorption.
