Removal of Heavy Metal Ions from Waste Water Using Modified Sands: A Brief Review

Article Preview

Abstract:

The modified sands compared with plain quartz sands possessed larger surface area and higher specific affinity towards heavy metal ions in waste water. Methods to synthesize modified sands have been briefly reviewed. Emphasis has been on the adsorption mechanisms and the characteristics of the modifying coatings which influence the absorbents’ efficiency and speciality.
