Determination of gallium by displacement substoichiometric extraction with labeled indium-oxinate in chloroform

A radiochemical displacement method for the determination of small amounts of gallium has been developed. The method involves the displacement of spiked (114mIn) indium from its oxinate in chloroform. The effects of various ions on the extent of displacement have been reported. By this process not, vert, similar6–28 μg of Ga(III) can be determined. Results are highly reproducible in the proposed method.
