A sorbent for antimony anions, consisting essentially of particles or granules of zirconium oxide having a distribution coefficient for antimony anions of at least 10,000 ml/g. The invention also provide a method of producing the new sorbent as well as methods of removing antimony and optionally tcchnctium from solutions. The coefficient of distribution is so high that the material can readily be applied to industrial use. The preparation process is straightforward and the sorbent can be produced from readily available materials at moderate conditions. |
