Photocatalysis for Water Treatment: A Sustainable Sanitation Access in Daily Life

Abstract

Enormous technological progress and widespread industrialization has made human life easier but at the cost of imbalance in our biosphere. Anthropogenic activities during the last century have engendered serious environmental issues including water pollution. Huge amount of a variety of toxic organic (synthetic dyes, antibiotics, pesticides) and inorganic (heavy metal ions) pollutants are constantly being discharged as agricultural runoffs or as industrial wastes from textiles, leather, cosmetic, paper, dyeing and printing industries into lakes, streams, rivers, oceans, and other water bodies thereby deteriorating water quality and adversely affecting both aquatic and human life.
