This paper shows a comparative study between the two radiation grafted chitosan derivatives viz. cross-linked chitosan (CRC) and cross-linked chitosan after hydrolysis (CRCH). These chitosan derivatives were used as solid phase extractors for several radionuclides. The uptake of 137Cs, 85,89Sr, 152E

A procedure for the pre-concentration and separation of trace amounts of Eu and U by solid phase extraction using Tulsion CH-90 resin (with imino diacetate functional group) has been developed. The determinations of europium and uranium have been carried out by a radiotracer technique using 152,154E

Transport of uranyl ion from HCl medium was investigated using 0.2 micron PTFE filters as the membranesupport and 30% alamine 336 in toluene as the carrier while distilled water was used as the strippant. In an experimentcarried out to understand the effect of the organic diluents, the observed tren
