Radiotracer studies on the uptake of strontium by poly(styrene-DVB) resins containing iminodiacetic acid groups

The uptake of strontium has been studied using two commercially available chelating resins containing iminodiacetic acid functional groups. The resins have been characterized with respect to moisture content, swelling behaviour, ion exchange and chelating capacities. The effect of pH, sodium and strontium concentrations on the uptake of strontium has been determined by carrying out batch equilibration tests. The suitability of using such a resin for removal of radiostrontium from radioactive waste solutions has also been tested in laboratory-scale column experiments. (orig.)
