Исследование сорбционных свойств природных и модифицированных глауконита и клиноптилолита

Abstract

The specificity and capacity of natural and modified by mixed nickel-potassium ferrocyanide (NPF) glauconite and clinoptilolite with respect to cesium and strontium radionuclides were studied. It was shown that the NPF-glauconite has higher cesium distribution coefficient and lower capacity than NPF-clinoptilolite. Natural and modified clinoptilolites have the highest specificity for strontium; strontium distribution coefficients are comparable within the error limits for both sorbents. Surface modifying of the clinoptilolite by the ferrocyanide phase leads to increase its capacity to strontium.
