Determination of Indium in Fluedust and Zinc Ore

A radiochemical displacement method has been developed for the determination of trace amounts of indium using radioactive zinc dithizonate as the reagent. The ease with which indium can be quantitatively collected over ferric hydroxide is put to advantage in developing the above method. The collection method in conjunction with the radiodisplacement method is used to determine indium in fluedust and zinc ore. The method is sensitive down to 2 μg indium in 10 ml of aqueous volume. © 1991, R. Oldenbourg Verlag
