title: Determination of iron(III) by displacement substoichiometric extraction with labeled silver-dipyridyl.
abstract: A substoichiometric radiochemical displacement method has been designed for the estimation of trace quantities of iron. The method involves the displacement of spiked ((110m)Ag) silver from its dipyridyl complex in n-butanol by iron(III) owing to the greater stability of iron-dipyridyl complex compared to that of silver-dipyridyl complex. The interference effects of various closely related foreign ions on the displacement reaction were found to be negligible, thus establishing the selectivity of the proposed technique over other standard analytical techniques available for the estimation of iron(III). The validity of this method has been established by successful estimation of iron from various complex matrices. Investigations have been made.
