The determination of gold, platinum, palladium and iridium in affined silver by the radioactivation method

Radioactivation method of gold, platinum, palladium and iridium determination in silver has been worked out. The method is based on the preliminary throwing down of silver macro basis in the form of AgCl and on the ability of precious metals to form stable chloride complex anions in definite conditions and not to be sorbed by cation exchange resins unlike many other metal cations.
