Abstract

Mercury is a specific concern worldwide because of its high toxicity. Exposure to mercury, even at very low concentrations, induces digestive, brain, kidney and endocrine system diseases, and it especially causes neurological diseases. Therefore, there is an urgent need for developing suitable technique to remove Hg2+ ion in water. In the conference, I would like to discuss the one step solution combustion synthesis of Iron oxide nanoparticles using various fuels such as oxalic acid, citric acid, urea, D-glucose, and glycine and its surface modification by silica coating followed by thiol (-SH) functionalization using L-Cysteine by ultra-sonication technique. Characterisation of thiol-functionalised core shell magnetic iron oxide nano-particles using XRD, FESEM, FT-IR, and UV-Vis technique is also discussed. Further, the effective removal of Hg2+ ion in aqueous solution using various amounts of functionalised core-shell magnetic will be revealed. After the adsorption processes, the Fe2O3@SiO2@SH nanoparticles recovery from the aqueous solution will also be highlighted. By utilising UV-Vis spectroscopic technique and a complexing agent dithizone ligand,the effective adsorption behaviour of Fe2O3@SiO2@SH nanoparticles for removal of Hg2+ ion in water will be discussed.

Audience take away:

1. Audience are enlightened about mercury ion ill effects and are made cautious about mercury ion contaminated water. 
2. The audience will be able to learn a very simple synthesis method for preparing core shell magnetic nanoparticles. 
3. It would definitely help the researcher to expand their research and the faculty for effective teaching about the applications of nanomaterials for water treatment. Further, it would be very useful for the delegates come from water purification industry.
4. It creates new concepts, ideas, curiosity, for more effective utilisation of magnetic nanoparticles for toxic metal ion removal.
