Development of chemically modified solid phase adsorbents for the metal ion separation in nuclear programme

The objective of separation process in metallurgy is to isolate the metal in its purest form. The purity requirement of metals for industrial and research needs has motivated the development of several innovative technological developments in separation science. Liquid-liquid extraction method, employing two immiscible liquid phases for achieving the separation of metal ions, has been utilizing for the metal ion separations in several metallurgical processes. In this report, the development of three independent chemically modified solid phase adsorbents is are discussed in detail. The solid phase adsorbents discussed in this report are (1) Polyamine resin modified with diglycolamic acid ligand (PA-DGAH) for lanthanide-actinide separation, (2) Anion exchange resins for the purification of plutonium and (3) Diethylenetriamine anchored polystyrene resin
