Speech Title: Advances in Nanoscience and Nanotechnology for environmental application
Nanotechnology has been widely explored recently due to the unique advancement in many areas of science and technology. Nanomaterials are the constituents of the engineered materials with desired size, which ultimately results in extraordinary physical and chemical properties, such as the unique optical, electrical, thermal and adsorption characteristics, etc., due to their ultra-small size. Large specific surface areas of smart composites can improve the detection sensitivity and miniaturize the devices in analytical procedures. Heavy metal contaminants released into the environment from many industries, such as electroplating and metal plating facilities, metallurgical operations, welding, alloy manufacturing, fertilizer industry, agricultural activities and tanneries. The heavy metals found in traces levels in the aqueous stream pose a significant toxicity to the health and environment.
Therefore, to remove hazardous heavy metals from water bodies and industrial wastewater has become a challenging task for researchers across the globe. There are various techniques available for the removal of heavy metals form water environment; these include, adsorption, ion-exchange, chemical precipitation, membrane filtration, electrochemical technology and reverse osmosis. Nevertheless, most of the treatment technologies are cost effective. However, among the above stated techniques, adsorption is one of the simple, easy to handle and low cost technique for removal of heavy metals. The present lecture will be focused on the recent development and advancement of nanotechnology for environmental remediation.
