Abstract

A method is described for the radioanalytical determination of traces of chlorine in aqueous solutions without radiochemical separation or purification. Using a gamma-spectrometer with monocrystal scintillator, the sensitivity of the analysis is about 1·10−8 g of chlorine/ml, the time of analysis being 15 minutes. For the selective determination of chlorine in aqueous solutions containing a large amount of impurities, a bicrystal scintillation sum-coincidence spectrometer was employed with 120×100 mm NaI(Tl) crystals and thus the38Cl cascade radiation could be used. Application of the sum-coincidence spectrometer allowed a reliable determination of 1·10−7 g of Cl/ml against a background of 1·10−5 g of Na/ml.
