Abstract: Electrodeionization (EDI) process was investigated for the recovery of Cs from AMP-PAN (Ammonium molybdophosphate Polyacrylonitrile). Ammonium sulphate solution was used as an eluant for the recovery of cesium from AMP-PAN with simultaneous regeneration of AMP-PAN. Two different modes of operation were studied in which eluant is passed through different compartments of the electrodialysis cell. One of the key parameters affecting the process like current density on Cs recovery was studied. The transport phenomena of the ions in the cell were explained using Nernst-Plank equation. Migration diffusion coefficients of the ions were determined by reducing the Nernst-Plank equation to migration term.

Keywords: Cesium, AMP-PAN, electrodeionization, recovery, regeneration.
