A simple, low cost method is described for the determination of gold(I) and platinum(I1) at the Kg level with 8-and h-fold amplification, respectively. The method is based on oxidation in a solution (pH 2.4-4.3) of gold(I) or platinum(lI) with aqueous potassium periodate, masking the unreacted perio
