Abstract

Neutron activation analysis combined with a simple exchange pre-separationis described for the determination of iodide and iodate in liquid samples. Iodide and iodate in seawater were separated by passing natural seawater through a small AG1-x4 ion exchange column. The effluent and washings of water were collected, acidified to pH 1.0, KHSO3 was added to the effluent to reduce IO3- to I-, and the effluent was passed through a new column. By eluting with diluted KNO3 solution and de-ionized water to remove Br-, Cl- andother ions, the columns were directly irradiated for the determination of iodide and iodate. For urine and milk, inorganic iodide was separated and determined by directly passing sample through the exchange column and washing. Under these experimental conditions, 10 ng is the detection limit for iodine.
