Professor Vinod Kumar Gupta from the University of Johannesburg will discuss the use of nanomaterials in waste water treatment in our monthly WIRC Colloquium seminar series in May.

Title: Role of nanomaterials in waste water purification
When: Wednesday 8 May 2019 at 1.15pm
Where: Room 3.16, Chancellors' Building, University of Bath (Location and maps)
Note: This event is free and open to all.

Abstract: Various technologies including reverse osmosis, ion exchange, precipitation, electrodialysis, adsorption, have been used for the removal of water pollutants. Among these, adsorption is supposed to be the best one due to its wide range of applications, ease of operation and inexpensive nature. Activated carbon has been used very frequently for the removal of various metal ions and other toxic pollutants from wastewater but it is very costly and in the recent years the search for the generation of alternate adsorbents has grown. Many of the starting materials for these replacement adsorbents are agricultural or industrial by-products, hence their use as secondary adsorbents contributes to the waste minimization, recovery and reuse.

Use of nanomaterials for waste water treatment is a new area and in the present lecture state of the art on the subject will be discussed along with examples of the work carried out by us in the area.

Speaker profile: Vinod Kumar Gupta is the South African Research Chair for Nanotechnology for Water and a Professor in the Department of Applied Chemistry at the University of Johannesburg. His research interests include waste water treatment, chemical sensors, environmental and electro analytical chemistry.

Professor Gupta has published over 600 research papers and four books with more than 60,000 citations and an h-index of 155 (Google Scholar). He was named one of the 2016 Highly Cited Researchers by Clarivate Analytics. He is an elected Fellow of National Academy of Sciences, India (FNASc) since 2008, and Fellow of the Royal Society of Chemistry (FRSC) since 2017.

  • Good day Sir. Please i will like to use your materials just for its literature to further work on other nano materials as it applies to water purification. Thank you for your understanding.
