title: Preparation of samples for measurement of 131I in environmental waters using pulsed column separation.
abstract: 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.
