<p><i>m</i>-Phenylene diamine-containing compounds were synthesized via a one-pot process and subsequently used as new precipitating agents (<b>PA1</b> and <b>PA2</b>). The precipitation of Pd and Pt was studied using <b>PA1</b> and <b>PA2</b> as metal precipitants. While <b>PA1</b> exclusively precipitated Pd from a HCl solution containing Pd, Pt, and base metals, <b>PA2</b> achieved precipitation of both Pd and Pt from the metal-containing HCl solution. Mutual separation of Pd and Pt was achieved by using <b>PA1</b> and <b>PA2</b> in the first and second precipitation steps, respectively. Separation tests at varying agent loadings revealed that Pd and Pt were precipitated by forming of an ion-pair composed of a metal chloro-complex anion (i.e., [PdCl₄]^2－ or [PtCl₆]^2－) and one precipitating agent molecule (i.e., divalent cation). The stoichiometric ratio of the ion-pairs was in agreement with the atomic ratios estimated from X-ray photoelectron spectroscopy results. Since the precipitation mechanism herein was based on the formation of an ion-pair, the cations of the precipitating agents only recovered Pd and Pt chloro-complex anions when the cations of the base metals were present in the solution. The different hydrophobicities of the precipitating agents enabled mutual separation of Pd and Pt.</p>
