Formation of hydroxamic acids in the radiolysis of tri-n-butyl phosphate containing nitric acid

“…For example, Di Furia et al [101] calculated concentrations in the range 10 28 to 10 29 M, too low to be significant in fission-product extraction. However, Zaitsev, et al [102] demonstrated the existence of concentrations as high as 4 6 10 24 M in the organic phase. Hao-xin et al [104] also showed that 10 24 M hydroxamic acids existed in 30% TBP/kerosene pre-equilibrated with 1 M HNO 3 followed by irradiation to 1500 kGy.…”

“…[57,69,101,102,103] It has been argued that hydoxamic acids do not occur in acid solution due to their rapid hydrolysis. For example, Di Furia et al [101] calculated concentrations in the range 10 28 to 10 29 M, too low to be significant in fission-product extraction.…”
