How do we measure the concentration of two different complex in the same solution: Rh2(SO4)3 and RhCl3?

12 November 2019 1 6K Report

Hi all. I have solution containing mixture of two complexes of rhodium Rh2(SO4)3 and RhCl3, the concentration about 100 ppb - 2 ppm each with matrix SO4 2- and Cl- about 2 M, is there any suggestion what characterization or method how to determine the concentration of each complex? many thanks.

Domenico Venuti

I will titulate with AgNO3 and indirectly have the concentration of Cl- and correlate that with the amount of RhCl3
