WebMay 10, 2014 · The thermal decomposition behaviour of neat TEHDGA, TODGA and their solutions in n -DD with and without DHOA and iD was studied in the presence and absence of nitric acid, using an adiabatic calorimeter. Neat DGAs underwent self-decomposition upon heating at and above 600 K, while the presence of nitric acid facilitated decomposition … WebMar 11, 2015 · Solutions of TODGA and T(EH)DGA in n-dodecane were subjected to γ-irradiation in the presence and absence of an aqueous nitric acid phase and analyzed using UHPLC-ESI-MS to determine the rates of radiolytic decay of the two extractants, as well as to identify radiolysis products. The DGA concentrations decreased exponentially with …

WebDegradation products of TEHDGA, obtained on γ-radiolysis of 0.2 M TEHDGA + 30% isodecyl alcohol/n-dodecane in the presence of nitric acid, were isolated and studied for … WebThe TEHDGA/ SiO2-P column showed earlier breakthrough than the TODGA/SiO2-P column. The adsorption capacities of the TEHDGA/SiO2-P and TODGA/SiO2-P adsorbents, calculated from each of breakthrough curves, were 0.04 and 0.06 mmol cm−3, respectively. The amount of feed solution supplied to the column should be adjusted based on these … WebN,N,N′N′ tetrakis-2-ethylhexyldiglycolamide (TEHDGA) sorbed onto 50-100 µm particle size Amberchrom® CG-71. The new resins have capacities for Eu of approximately 0.086 mmol/mL of bed and are quite stable to extractant leaching. The resins were characterized by measuring the batch uptake of actinides, lanthanides and yttrium, mounting putty for posters
