Preparation of samples for measurement of 131I in environmental waters using pulsed column separation.
The method is based on the selective separation and effective preconcentration provided by the pulsed column bed technique. The pulsed bed is made of a cylindrical packing of resilient open-cell polyurethane foam impregnated with a long-chain tri-n-alkylamine: iodine complex. Radioiodine is measured directly in the pulsed column with a conventional scintillation detector and gamma-ray spectrometer. The technique facilitates the separation process under field conditions and can also be conveniently automated.
