Complete removal of radioactive cations by standard mixed bed ion exchange resins is sometimes not achieved in liquid radwaste systems. Based on a literature survey, acrylic fibers impregnated with manganese dioxide were chosen as a media warranting study of their ability to adsorb the cations present in radwaste systems in the hope of improving performance of such treatment processes. A system to produce impregnated fiber with a heavy MnO[sub 2] loading was designed, constructed, and operated. The system produced fiber at an average fiber loading of 22.5 percent MnO[sub 2] by weight. Leaching tests made on the MnO[sub 2] fiber exhibited no signs of soluble manganese, insoluble MnO[sub 2], acrylonitrile leaching or fiber loss. Laboratory testing has been performed on the adsorption of calcium, cadmium, cesium, cobalt, iron, and manganese on MnO[sub 2] impregnated fiber. Removal of metals from solution was measured at levels specific for each metal tested. The removal efficiency when they were present in combination was also evaluated.
