Nano-Particle-Mediated Wastewater Treatment: a Review
2017
Ghosh, Ankita | Nayak, Ashish Kumar | Pal, Anjali
Nowadays, due to increase in worldwide population and rapid urbanization, water demand in the region is increasing fast while water quality is deteriorating. The physical, chemical, and biological characteristics are changing in a fast way due to the accumulation of contaminants such as heavy metals, synthetic dyes, and organic and inorganic materials. This makes the water harmful for the biotic and abiotic components of the ecosystem. Various noble approaches have been employed by the researchers in order to replace the traditional wastewater treatment methods. In this regard, nano-technology has occupied a central position in the areas of research. The term “nano-technology” is a branch of science which acknowledges the manipulation of materials at nano-scale. These materials may have large specific surface area, high reactivity, degree of functionalization, size-dependent properties, etc., which make them suitable for execution in water purification and wastewater treatment. This paper briefly reviews the current advances and application of nano-materials for wastewater treatment. Here, various types of nano-materials such as carbon nano-tubes, MnO₂ nano-sheets, graphene composites, metal oxides, antimicrobial nano-materials, and photocatalysts, which are employed in the field of wastewater treatment, have been dissertated.
