A method has been investigated for the simulataneous determination of trace quantities of the platinum group metals in aqueous solutions derived from ores and related plant materials. The method is applicable to both high and low grade materials, and it is necessary in the case of the low grade materials to do a preliminary collection of the platinum group metals in a nickel …
