A colorimetric method is described for the determination of Tc in solutions from the processing of irradiated reactor fuels. The method is applicable to amounts of Tc from 5 to 200 ..mu..g/ml; however, the absorbance of the Tc-SCN complex in chloroform is linear from only 1 to 20 ..mu..g/ml of Tc in a 2-ml final volume. The complex absorbs at 513 nm, has a molar extinction coefficient of 46,000, and is stable for several hours. The method is highly specific for Tc. (BLM)
