Abstract

A 13C-NMR study was performed on polyacrylic acid (PAA) gel swollen in water in the presence of some di- and trivalent ions (Ca2+, Sr2+, Ba2+, Zn2+, UO 2+2 , Al3+). As concentration of metal ions grows, the NMR signals (CH2, CH, COO) gradually broaden up to the spectrum disappearance. This is the moment when the gel collapses and the metal ion saturation occurs. The information obtained from 13C-NMR can be used in radioactive waste treatment procedures.
