摘要：

Local structure of Fe(III), Cr(LU), and Zn(II) cations has been determined on the amorphous sample by means of the difference method used for liquid systems. We recorded energy-dispersive X-ray diffraction spectra of a chelating resin (Chelex 100), containing paired iminodiacetate ions coupled to a styrene-divinylbenzene support, in several ionic forms. Coordination geometry of Fe(III), Cr(III), and Zn(LI) metal cations with Chelex 100 resin ligand sites, and conformation of the ligand groups have been determined.
