Composite materials made from polyacrylonitrile binding polymer and solid extracting agents with functional groups of diphenyl-carbamoylmethylphosphine oxide bonded to a platform of calix[4]arenes and cobalt bis(dicarbollide) cluster anion were tested for application in column chromatography. They exhibited high affinity for americium, plutonium, uranium, and europium ions in nitric acid solutions. However, europium distribution isotherm in 3 M HNO3 indicated low capacity and unsatisfactory employment of the functional groups. Similar material with octyl(phenyl)-N,N′-diisobutylcarbamoylmethylphosphine oxide extracting agent had both high affinity and uptake capacity.
