Abstract

The interaction of hafnium(IV) and thorium(iv) with humic acid, HA, is studied using EXAFS and compared to the interaction of these metal ions with carboxylate groups of the cation exchanger Bio-Rex70. Fourier-f'fltered Hf and Th I-,3 edge transmission EXAFS for the first oxygen shell is analyzed. F...
