Recent advances in environmentally benign hierarchical inorganic nano-adsorbents for the removal of poisonous metal ions in water: a review with mechanistic insight into toxicity and adsorption
C. Manjunatha
Abstract
Water contaminated with heavy metal ions, As<sup>3+</sup>, Pb<sup>2+</sup>, Cr<sup>6+</sup>, Cd<sup>2+</sup>, and Hg<sup>2</sup> is known to be toxic or carcinogenic. We review the mechanistic toxicity and carcinogenicity of these ions and hierarchically architectured inorganic nano-adsorbents for their removal are explored.
