At present working on “Development and functional estimation of new thiacalix[n]arenes based extractants for base-metals/rare-metals recovery from automotive catalyst residues”
Developed novel synthetic routes for the synthesis of lower and upper rim substituted thiacalix[n]arenes via SNAr reactions/Mannich reaction and characterized them by the combined use of NMR and single crystal X-ray techniques.
Developed novel silica/chitosan composite, alumina/chitosan composite, nano- hydroxyapatite/chitosan composite via sol-gel reactions and characterized them by the use of BET, TEM and X-ray techniques.
In addition, prepared various modified multifunctional chitin/chitosan and synthetic polymeric resins for toxic ion removal.
Carried out various functional group inter conversions and prepared amino terminated hyper branched dendritic polyamidoamine chitosan beads (up to 3rd generation) were prepared by Michael addition of methyl acrylate to amino groups on the chitosan surface and amidation of terminal ester groups by ethylene diamine.
Experience in both column and batch adsorption studies, solving various sorption isotherms, thermodynamic parameters, sorption kinetics and arriving suitable mechanism.
