The direct dissolution of voloxidized used nuclear fuel (UNF) into an organic solution-comprised diluent and specialized extractants-poses a promising alternative to the traditional liquid-liquid solvent extraction approach reprocessing UNF. However, moving removes presence concentrated nitric acid aqueous phase, which has been shown significantly influence radiolytic longevity extractants in conventional flowsheets. Given limited knowledge radiation effects under conditions, here we present...
Two classes of used nuclear fuel (UNF) extraction ligands, amide (DEHBA, DEHiBA, HONTA) and organophosphorus (CMPO, HEH[EHP], TBP), were selected to study radiation induced damage at picosecond nanosecond timescale...
Radiolytically generated solvent holes (Dodecane˙ + ) mostly attach faster than 10 ps to the extractant molecule TODGA, followed by rapid degradation of TODGA˙ in competition with hole transfer low IP indicators.
Radiation chemical studies of esculetin (E), a dihydroxycoumarin derivative, were performed using pulse radiolysis technique employing kinetic spectrometer and quantum calculations. Both the oxidizing radicals, hydroxyl (˙OH) azide (N3˙) reducing radical hydrated electron (eaq-) hydrogen atom (H˙) reactions E used for present study. The reaction ˙OH N3˙ radicals with produced transients that absorbed at 410 nm; additionally, another broad band 510 nm was observed reaction. formed phenoxyl...
The use of aluminium has made significant impact in our life by virtue its attractive properties. lack essentiality biosphere indicated that accumulation above certain level is undesirous. Esculetin (6,7-dihydroxy coumarin) an excellent ion chelator and the chelation interaction was studied exploiting absorption fluorescence behavior esculetin. In presence ion, band esculetin shifted from 350 to 380 nm suggesting possibility complex formation. intensity at 466 significantly quenched ion....
