Description
A new procedure for isolation and determination of 90Sr in real natural samples is presented. It consists of bringing natural samples in a soluble form suitable for separation on an ion-exchange column, separation of calcium from strontium by means of the anion exchanger Amberlite CG-400 and 0.25M HNO3 in methanol as eluent for calcium, and the determination of 90Sr using a low level β-counter after elution with H2O, scavenging steps and SrCO3 precipitation. The method was tested with IAEA standards of natural samples with known contents of 90Sr, and water samples, where the concentration of 90Sr was previously determined by the standard IAEA procedure. The results obtained show that it is possible to isolate and determine low levels of 90Sr in natural samples. The procedure is favorable because of the simple separation of radioactive strontium without using fuming nitric acid. (author) 9 refs.; 2 tabs
