3,5-Di-Br-PADAT is a sensitive and selective reagent for Pt. It forms stable complex frompH 6. 5 to 0.6 M HCI and do not decompose even in 4 M HCl media. Cu~(2+) Ni~(2+) and Co~(2+) donot interfere, the existance of considerable amounts of other platinum metals is allowed. Al-though Fe~(3+) interferes with the determination, it can be eliminated by EDTA, This method ispreferable for the determination of Pt in ores.
