A. Yuchi et N. Yoshida, Adsorption of tetravalent metal ions to chelating resins containing iminodiacetic acid groups, B CHEM S J, 73(8), 2000, pp. 1841-1842
With respect to the selectivities, the compositions of species formed by th
e adsorption of tetravalent metal ions (M4+) to chelating resins containing
iminodiacetic acid groups (-LH2) were estimated from the shapes of the ads
orption curves and the infrared absorption spectra of the polymer complexes
: [-LM(OH)(2)] for Zr4+ and Hf4+, while [(-LH)(4)M], [(-L)(-LH)(2)M], and [
(-L)(2)M] for Th4+.
