摘要：

The uptake capacity towards heavy metal ions in aqueous sulfuric acid of fourteen crosslinked polymer resins has been studied. Some resins contain poly(amido-amine)s or poly(amido-aminoacid)s crosslinked with 1,4-diaminobutane, others contain free NH//2 or oxime groups on a tightly crosslinked structure. All the resins are highly swellable in sulfuric acid solution and, except for the resin containing oxime groups, degrade in a 7-20 days period. All the resins show capacity of retention for Ni**2** plus in 1. 53 sulfuric acid. The resins of the first group also show some selectivity towards several metal ions. For the resin containing oxine groups, the retention seems to occur via a coordination mechanism.
