Y. Yang et al., SYNTHESIS AND CHARACTERIZATION OF THE PERIODATO COMPLEXES OF THORIUM(IV) - (MTH)-TH-I(H2IO6)(OH)(2)CENTER-DOT-4 H2O, Radiochimica Acta, 80(3), 1998, pp. 147-150
Novel complexes of tetravalent thorium with periodate have been prepar
ed from aqueous caustic potash solution. Chemical analysis indicates t
hat the composition of these complexes possess the formula: (MTh)-Th-I
(H2IO6)(OH)(2).4 H2O (M-I = Na+, K+, NH4+), and the complexes have bee
n characterized by means of IR, Raman, W-vis spectra and thermal analy
sis.
