Abstract

A rapid, inexpensive, method for multi-element trace determinations in reactor moderator heavy water is described. Samples were analyzed for copper, silver, gold and mercury at the low μg l−1 level using differential-pulse stripping voltammetry (DPSV); these ions are kept below 25 μg l−1 to avoid possible corrosion to the reactor vessel. A high concentration of aluminum and iron in the samples prevented analysis by inductively coupled plasma spectrometry; the DPSV method described is unaffected by these interferences. As the method involves a solution-phase determination, it has the important advantage of not volatilizing highly tritiated samples.
