Determination of palladium by stripping voltammetry in raw gold ores

Anodic stripping determination of Pt(IV) based on the anodic oxidation of In from electrochemically deposited Pt–In alloy phases

“…According to the literature data [4,5], indium and platinum form the following intermetallic phases: Pt 3 In, Pt 2 In, Pt 3 In 2 , PtIn 2 ,PtIn, It has been shown earlier [6] that the peak potential shift for the electrochemical oxidation of the less noble component of intermetallic phases can be described by a general equation, which can be written in the special case of In-Pt as follows:…”

“…The mixing heats of alloy formation can be approximately calculated from the energies of formation of covalent bonds between the metals using Pauling's correlation equation [6]:…”

Determination of Platinum and Palladium in the Presence of other Metals in the Mineral Raw Materials

“…Increasing the palladium anodic current peak when introduced to the background electrolyte (0.1 M HCl) of oxalic acid is an average of two times (curve 2). Table 1 shows the results for the voltammetric determination of palladium (II) using various methods to eliminate the influence of gold [6]. As seen from Table 1, the error in the analysis results less after recovery of gold (III) ions from solution by UV irradiation in the presence of oxalic acid.…”

Estimation of the composition of electrolytically prepared intermetallic bismuth–platinum deposits

“…It has been shown earlier [3,10] that the peak potential shift for the electrochemical oxidation of the less noble component of intermetallic phases can be described by a general equation, which can be written in the special case of Bi-Pt as follows:…”
