Colormetric determination of technetium in aqueous solutions - approved 1973

Book ·
OSTI ID:6832555
Quantitative determination of technetium in known volumes of aqueous solutions of nuclear fuel that contain radioactive nuclides is described. These solutions are from the processing of irradiated nuclear fuel and from the laboratory studies on irradiated nuclear fuel. The method is applicable to solutions that contain a minimum of 5 ..mu..g of technetium per sample, but it will detect as little as 0.4 ..mu..g. The method as described is limited to sample volumes of 2 ml or less, but reagent volumes can be scaled to accommodate large sample aliquots. This method is based on measurement of the absorbance of the technetium thiocyanate complex in chloroform.
