Summary on Grant Application Form
Magnetic materials are electrodeposited from electrolytes containing expensive and strategic cations such as Ni2+, Co2+, Fe2+, and anions such as citrates and sulfamates. The electrodeposition process demands stringent regulation of these anions and cations because the magnetic properties of the electrodeposits are critically dependent on electrolyte chemistry. In view of these restrictions, large quantities of electrolytes are generated as waste during this process.We propose to exploit electrodialysis to separate out metal cations as well as anions which can be recycled back into the process stream thereby minimising waste. The research work will concentrate on the identification of appropriate ion-exchange membranes and procedure for the separation and the performance of the recycled electrolyte.
