Fire Assay using copper collectors

Fire Assay using copper collectors

Fire Assay using copper collectors

(OP)
Nickel Sulphide technique is a classical one with many advantages. I am investigating Copper collection in Platinum group metals (Pt, Pd, Rh, Ru, Ir, {Au}).
The process is carried out similarly to Nickel sulphide collection, where sample is done through fire assay, recovered copper alloy is either directly digested in conc. hydrochloric acid, or pulverised into powder, before digested in HCL.
The process of copper collection seems to have a big drawback when measuring on ICP-OES (due to copper interfierence), making interpretations of spectra is difficult even under very close matrix matched conditions.

Do you have any suggestions on how to reduce such spectral interferences, (i.e. edit the method)?

Help would be greatly appreciated, thank you. :)
