Abstract  

Determination of copper/II/ by radiochemical displacement of labelled cobalt from cobalt-o-hydroxybenzaldehyde isonicotinoyl hydrazone /Co-BIH/ complex has been studied. Borate buffer of pH 5 was found to be a suitable medium for quantitative displacement. 10–70 g of copper could be determined. The effect of various foreign metal ions on the determination has also been studied.

Abstract  

A new radiochemical displacement method has been developed for the determination of EDTA /ethylene diamine-tetraacetic acid/. The displacement of labelled zinc from Zn:PAN complex by EDTA at pH 5.5 in borate buffers can be conveniently utilized for the determination of 50–150 g of EDTA. Effects of diverse ions on the determination have also been tested.

Abstract  

The possibility of determination of microgram quantities of palladium by radiochemical displacement of labelled Zn from Zn: 1-/2-pyridylazo/-2-naphthol comples has been explored. Conditions for quantitative displacement, a calibration in the range of 40–140 g of palladium and the effects of diverse ions have been reported.

Abstract  

Determination of cadmium by radiochemical displacement of zinc from a labelled ZnPAN complex has been studied. pH 5.5 in borate buffer was suitable for quantitative displacement. The effects of diverse ions on the displacement reaction are also reported.
