A quick and precise heterometric microdetermination of traces of palladium in metals with nitron

A heterometric study was made of the reaction between palladium chloride and nitron in thiocyanate solutions in the presence of excesses of various masking agents.A method is presented for the hetorometric determination of ~0.5 mg palladium in 20 ml aqueous solution with nitron, which can be carried out within 5–10 mn. The solution to be analysed may in general contain ~99.5% of the following foreign metals as cations: Ca⁺², Ba⁺², Mg⁺², Zn⁺², Mn⁺², Co⁺², Ni⁺², Al⁺³, Fe⁺³, Cr⁺³, UO₂⁺², Cu⁺², Cd⁺², Hg⁺², Pb⁺², Tl⁺, Sb⁺³,Bi⁺³, Th⁺⁴, Ce⁺³ and ZrO⁺². The error is between 0 and 1%.
