ADSORPTION OF RADIOSTRONTIUM BY SOME SOILS AND SOIL MATERIALS
Adsorption of the radioactive fission product strontium was studied with 50 natural materials frequently found in soils, from solutions containing no extraneous cations and in the presence of stable strontium or calcium ions. The greatest adsorption of radiostrontium was shown by the clay minerals (montinorillonite, kaolinite, halloysite) micas, hydrous micas, peat, pyrolusite, phosphorite, and nepheline syerite. Therefore, when radiostrontium falls on soils, one expects highest contents where these minerals are present, other things being equal. It was established that the ability of natural materials to adsorb radiostrontium strongly depends on a large exchange capacity. The presence of calcium, even as little as 100 mg/l, considerably reduces the adsorption of microquantities of strontium from solution. (Public Health Eng. Abstr., 46: No. 8, 1961).
