Determination of .sup.129I using volatilization method and liquid scintillation spectrometry

A simple and rapid separation method for .sup.129I determination in radioactive waste samples was developed. Suitable conditions for iodine volatilization were tested. Iodine was trapped in 1.5 mol L.sup.-1 NaOH and precipitated as PdI.sub.2·H.sub.2O by addition of PdCl.sub.2 with recoveries higher...

Zusammenfassung:A simple and rapid separation method for .sup.129I determination in radioactive waste samples was developed. Suitable conditions for iodine volatilization were tested. Iodine was trapped in 1.5 mol L.sup.-1 NaOH and precipitated as PdI.sub.2·H.sub.2O by addition of PdCl.sub.2 with recoveries higher than 80%. The method was applied for analysis of contaminated soil, radioactive sludge, evaporator concentrate and heterogeneous waste samples from nuclear power plants in Slovak Republic. .sup.129I was measured on liquid scintillation counter TRI CARB 2900 TR using Ultima Gold AB scintillation cocktail.
