Abstract
USE OF NANOPARTICLES IN WASTE WATER TREATMENT: A REVIEW
Dr. Richa Sharma*
ABSTRACT
The scarcity of water throughout the world has led to the recentresearch for water security and safety. The water resources are mainlypolluted due to the discharge of the industrial effluents, thus making itunusable for further use without treatment. The use of polluted watermay pose severe threat to the health and environmental hazards urgingfor the suitable technology to treat such waste water. The technologiesavailable for the treatment of dye effluent in the water is timeconsuming, cost-intensive and less effective. Thus, nano particles dueto their chemical reactivity and excellent surface properties have emerged as a betteralternative for the dye removal. This paper reviews the potential of nanoparticles in dyeeffluent treatment. Though studies have revealed that the treatment of waste water with silvernanoparticles leaves traces of toxicity into water after treatment. The further research onmitigation of toxicity induced due to the use silver nanoparticles will decide the fate of use ofsilver nanoparticles for dye treatment.
