spot test with stanous chloride

[arthur kierski]

i make many tests a day with stanous chloride in a spot plate for gold and palladium----then i add these tests in a becker with some water and ar---this becker contains gold and pd .How can i precipitate the gold and pd from this becker?

 

[lazersteve]

Precipitate the solution with zinc or copper, incinerate the resulting powder to red heat (do not melt!!), treat the powder with hot 35% HNO3 to extract the Pd, and finally dissolve the gold in AR.
