Diphonix is a new dual-mechanism polyfunctional resin containing sulfonic and gem-diphosphonic acid groups. In Part 1 of this series the effectiveness of Diphonix in removing actinide ions from very acidic solutions was demonstrated. In this paper we report on the uptake of various transition and post-transition metal ions with Diphonix and two other resins for comparison. The results show that Diphonix has a very high affinity for Fe(III) and Cr(III) in very acidic solutions. From neutral solutions Diphonix exhibits a high selectivity for lead and transition metals over calcium. Conditions for efficient stripping of the investigated ions have been found.
