Research Interests

Membrane based separation techniques: Synthesis, characterization and application; Quantum Chemical & Density Functional Theory (DFT) based calculation to investigate nature of chemical bonding in metal-ligand systems.

Brief Research Profile

Selective recovery of metal ions from solution has always been a challenging task for separation scientists. Various techniques have been applied for this purpose viz. solvent extraction, ion-exchange, extraction chromatography, membrane based techniques, etc. Liquid membranes offer several advantages over others, such as low organic requirement, ease of operation, easy scale up of process, etc. Liquid membranes have been applied for the recovery of Cesium & Strontium from acidic solution. Various experimental and theoretical studies were carried out and the major findings are as follows-1. Liquid membrane techniques are effective for selective removal of metal ions from the solutions.2. The process can be scaled up for the larger volume of solution.3. Mathematical model was developed which can simulate the experimental transport profiles within the acceptable error limits. The present research interest lies in the application of membranes for the remediation of industrial waste effluents by removal of toxic heavy metal ions (such as Pb, Hg, Zn, Ni, etc) which are environmentally hazardous.
