Detection and identification of solids, surfaces, and solutions of uranium using vibrational spectroscopy
2018, Coordination Chemistry ReviewsCitation Excerpt :Using the equation from Bartlett and Cooney [63] (ν1 = 0.89·v3 + 30.8 (cm−1)) results in an average difference of 11.2 cm−1 between the predicted and experimentally determined v1 frequencies. In comparison, the predicted and experimental values differ by ∼3.2 and ∼3.1 cm−1 when utilizing the McGlynn et al. [145] (ν1 = 0.89·ν3 + 21 (cm−1)) or Bagnall and Wakerley [150] (ν1 = 0.912·ν3 − 1.04 (cm−1)) relationships, respectively. The largest differences were observed with the densely packed solids, Rb2UO2Cl4·2H2O and Cs2UO2Cl4 using the Bagnall and Wakerley [150] and McGlynn et al. [145] equations where average differences were 11.8 and 8.7 cm−1, respectively.
Uranium stripping from tri-n-butyl phosphate by hydrogen peroxide solutions
2013, HydrometallurgyCitation Excerpt :The IR spectrum shows the following major regions: a weak broad band in the 400–550 cm− 1 region due to the deformation of P = O; an asymmetric and a symmetric bending of the ONO group at 669 and 722 cm− 1, respectively; weak bands at 735 and 771 cm− 1, which are assigned to CH2 groups; small bands at 867 and 959 cm− 1, which are assigned to the symmetric and asymmetric stretching vibrations of the uranyl group, respectively; a C–C stretching vibration band at 911 cm− 1; stretching vibrations of the P–O–(C) group at 992, 1029 and 1061 cm− 1; bands at 1120 and 1151 cm− 1, which are assigned to the stretching vibrations of the C–O–(P) group; stretching vibrations of the P = O group at 1236, 1272 and 1285 cm− 1; bands in 1350–1500 cm− 1 region, which are characterized by the bending vibrations of CH3 and CH2 groups; and bands in the 2800–3000 cm− 1 region due to the symmetric and asymmetric stretching vibrations of CH3, CH2 and CH groups. The IR bands assignments are consistent with those in the literature (Bagnall and Wakerley, 1975; Borkowski et al., 2002; Ohwada, 1968; Piras, 2002; Sato, 1965). The peak in 2250–2550 cm− 1 region is assigned to uncompensated interference due to carbon dioxide in the atmosphere of the sample compartment Fig. 5 and Fig. 9).
