Nanomaterials for Removal and Speciation of Chromium

Materials, Год журнала: 2025, Номер 18(7), С. 1485 - 1485

Опубликована: Март 26, 2025

The removal of chromium compounds, particularly its more toxic Cr(VI) form, from industrial wastewater is important as it causes serious environmental and health issues. Adsorption processes have attracted continuous interest for solving these problems due to the diverse range various adsorbents. Nanomaterials are increasingly employed novel sorbents they a large specific surface area high chemical stability. Functionalization their by covalent or noncovalent interactions with other components, grafting doping heteroatoms can enhance separation efficiency. This paper aims provide insights into recent progress in application nanomaterials aqueous solutions speciation analysis it.
