the Pd is in the form of the finely divided metal itself. like Pt, a black powder of the element is formed by reduction. it will work great in all reactions calling for Pd powder,supported Pd or Pd sponge, as long as it hasnt been contaminated by S cpds. it is hard to beelieve it was "discarded" the value is, um, a bit higher than most scrap metals. this would be like throwing away 250000. to find out how much you have, boil in HCl and evap soln, calc Pd from wt of the PdCl2.
