Özet:

 

A new chromogenic reagent, 2-(2-quinolylazo)-5-dimethylaminoaniline  (QADMAA) was synthesized.  A sensitive, selective and rapid method for  the determination of palladium based on the rapid reaction of  palladium(II) with QADMAA was developed.  In the presence of 0.5-2.5  mol L-1 of hydrochloric acid solution and cetyl trimethylammonium  bromide medium QADMAA reacts with palladium to form a violet complex  with a molar ratio of 1:2 (palladium to QADMAA).  The molar  absorptivity of the chelate is 1.35x105 L mol-1 cm-1  at 600 nm.  Beer's law is obeyed in the range of 0.01 to 0.6 m g  mL-1.  The detection limit is 1.2 m g L-1.  This method has  been applied to the determination of palladium with good results.
