摘要：
A rapid and sensitive method has been developed for the determination of microgram amounts of chromium based on the radiochemical displacement of Zn-65 from labeled Zn-[1-(2-pyridylazo-2-naphthol](2) complex by chromium. The effect of pH on the displacement of Zn-65 was studied. 5-65 mu g of chromium could be determined with great accuracy. The effect of various ions on the displacement of Zn-65 by chromium was investigated and the method developed was utilized for the determination of chromium content present in geological water samples. The results were compared with values obtained by Atomic Absorption Spectrophotometry.
