Fractionation of Colloidal Matter of Stratal Waters during Deep Burial of Radioactive Wastes

详细

The paper presents ultrafiltration and microscopic study of colloidal matter from radioactive waste disposal site at the Siberian Chemical Plant. It is established that most part of actinides (55–90%) are mainly bonded to colloidal particles, whereas only 20% natural uranium are bonded to >5–µm particles at the background site. In general, the retention of transuranium elements (TUE) from contaminated waters by membranes with pore size from 200 to 5 nm increases with increase of anthropogenic uranium content in water
