Abstract:
Adsorption property of graphene oxide (GO) towards cationic dyes such as methylene blue (MB) and rhodamineB (RhB) has been investigated experimentally. GO structure used in our study is decorated with experimentallyobserved oxygen functional groups (OFGs). Fast and effective adsorption of MB with GO in single and binarysolute solution has been observed experimentally. In support of our experimental data and to understand theinteraction of adsorbent (GO) and dye, density functional theory (DFT) calculation has been used for calculatingindividual binding energy of GO, GO/dye in aqueous medium. Further, study on dye interaction with GO revealsthat adsorption was facilitated by presence of oxygen functional group through electrostatic interactions.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
