Direct-current plasma emission spectrometric analysis of platinum group metals in solutions from automobile catalyst shows significant enhancement of analyte values Addition of a lithium buffer does not remove the interference The only matrix constituents in these solutions were aluminum and magnesium, both of which were found to cause enhancement in the determination of platinum, palladium, and rhodium A buffer consisting of 3500 mg/L lithium and 2500 mg/L lanthanum removed the enhancement effect of both magnesium and aluminum on these metals 8-hydroxyquinoline also reduced the degree of interference due to aluminum, although not as efficiently as lanthanum, indicating that formation of compounds in the dc plasma is a possible source for the observed interference

Platinum Group

A singlecrystal X-ray structure determination of (2,2′-bipyridine)dichloropalladium(II), iso- morphous with the 'yellow' form of the platinum(II) analogue, has been carried out. Crystals are orthorhombic, Pbca, a 18.144(5), b 15.952(5), c 7.494(2) A, Z 8, 1113 diffractometer reflections being refined by full matrix least squares to a residual of 0.052. The planar molecules of PdCl2(bpy) are stacked into columns along the c direction, at a separation of c/2, neighbouring molecules in the stacks being related by glide planes with Pd…Pd separations of 4.587(2) A.
