FIELD: transportation.
SUBSTANCE: invention relates to ion-exchange materials capable of removing radionuclides from water. Method for selective removal of strontium radionuclides from a water stream containing strontium cations and at least one of sodium cations, potassium, calcium or magnesium is to bring the water stream into contact with amorphous titanium silicate, which is obtained by contacting a solution of a soluble titanium salt with sodium silicate and a sufficient amount of alkali under vigorous mixing.
EFFECT: invention provides an effective and cost-effective removal of strontium radionuclides from water streams.
