摘要：

A rapid, simple, selective and sensitive method for the determination of palladium in trace amounts has been developed, based on the reaction of 2-(2-hydroxyimino-1-oxoethyl)furan [alpha-isonitroso-2-acetyl-furan] with the metal ion in acetic acid. The intense yellow complex is quantitatively extractable into chloroform, whose absorbance is measured at 425 nm. The method is free from the interference of a large number of other metal ions. It obeys Beer's law in the range 0.0-3.8 mu g Pd mL(-1) with Sandell's sensitivity of 0.003 mu g Pd cm(-2). The ratios of metal to ligand in the extracted complex are 1:1 and 1:2. The analysis of various samples has been carried out with satisfactory and reproducible results.
