Use of fibers and fabrics for separation of radioactive isotopes

Results of investigations into extraction from solutions of the most genetically dangerous long-lived isotopes - cobalt-60, cesium-134, strontium-90, on low-base anionite (sorption exchange capacity is 5.7 mg x eq/g) are presented. Sorption dependence on low-base anionie of cesium-134, cobalt-60, strontium-90 from pH of solution is studied. It is shown that in 4-8 pH range sorption achieves its maximum value (99.8%). The effect of changes of CsNO3 microconcentration on the degree of cesium-134 extraction from solution on low-base anionite is studied. It is established that increase of CsNO3 concentration from 10-5 to 10-3 g x eq/l brings about the rise in the amount of isotope absorbed by 100 g of sorbent (q) and the degree of extraction practically does not change
