Chromatographic Separation of Actinides and Fission Products

Decontamination Study of Some Noticeable Fission Products in the Actinides Recovery by Truex Process

Decontamination performance of some noticeable fission products from TRU elements by the TRUEX process was calculated with a multistage extraction simulation code. The batch extraction data of molybdenum, palladium, antimony, and cerium, which have been obtained in our related TRUEX studies, were provided for the calculation. For uranium, plutonium, and americium, literature data were used. A m...

Transmutation of Fission Products

Studies of transmutation of long-lived fission products by accelerator and by fission reactor at PNC are described. Four transmutation methods by accelerators are compared in terms of transmutation energy and transmutation rate. A super-powered electron linear accelerator which could transmute a large quantity of fission products has been studied and development of PNC test linac in this line i...

Chromatographic separation of glycated nucleotides.

A high-performance liquid chromatographic method for the separation of nucleotide glycation reaction product(s) has been developed. The product(s) arising during in vitro glycation of a nucleotide (AMP, GMP or CMP) with a reducing sugar (ribose or glucose) were clearly resolved from the non-glycated constituents of the reaction mixture. The peak(s) of the glycated product(s) increased when an a...

Chromatographic Separation of the Diastereoisomers

Reduction of folic acid to the tetrahydro level introduces a second asymmetrical center into the molecule at carbon atom 6.1 The resulting tetrahydrofolate, and subsequent derivatives, prepared chemically consist of dl mixtures that are only 50% active in biological reactions. The need for fully reactive isomers of reduced folates led to the enzymatic synthesis of tetrahydrofolate from 7, %dihy...
