[en] In the present work the sol-gel method has been used to synthesize zirconium, titanium, and tin phosphates and hexacyanoferrates(II) in spherical form. The uniform distribution of the macroelements over the cross section of the granules has been investigated. X-ray microprobe analysis (XRMA) was selected as the main method of analysis. Methods for the statistical treatment of the results of the measurements have been developed for this approach which has been used successfully for the quantitative evaluation of the homogeneity of objects such as alloy steels and alloys. It is found that the homogeneity level of the sorbents with respect to Zr, Ti, Sn, P, and Fe does not exceed -/+1.5 rel.% for a bilateral confidential probability of 0.99
