title: Development and application of an on-line sequential injection system for the separation of Pu, 210Po and 210Pb from environmental samples.
abstract: An on-line sequential injection (SI) system was developed, which can be widely used for the separation and pre-concentration of target analytes from diverse environmental samples. The system enables the separation time to be shortened by maintaining a constant flow rate of solution and by avoiding clogging or bubbling in a chromatographic column. The SI system was successfully applied to the separation of Pu in IAEA reference material (IAEA Soil-6) and to the sequential separation of 210Po and 210Pb in a phosphogypsum candidate reference material. The replicate analysis results of Pu in IAEA reference material (Soil-6) obtained with the SI system are in good agreement with the recommended value within 5% of standard deviation. The SI system enabled a halving in the separation time required for radionuclides investigated.
