    Notes: The adsorptive voltammetric behavior of the RhIII-2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP) complex was studied with the linear scan technique in a solution of 0.01 mol/L NaOAc-0.07mol/L HOAc-35% ethanol (supporting electrolyte, pH 4.2).A very sensitive and selective adsorptive stripping voltammetric method for the determination of Rh is described. The proposed method can be used for determining trace rhodium in the concentration range 7.8 × 10-9-9.7 × 10 -7 mol/L without interference from other noble metal ions. At the same time, a simple oscillopolarographic procedure for determining Rh in the same electrolyte is also proposed.

    Voltammetric behavior and determination of bismuth on sodium humate modified carbon paste electrode (1997)
    Weinheim : Wiley-Blackwell
    Electroanalysis 9 (1997), S. 645-649

    Keywords: Modified carbon paste electrode ; Cyclic voltammetry ; Differential pulse stripping voltammetry ; Sodium humate ; Bismuth ; Chemistry ; Polymer and Materials Science

    Notes: The preconcentration and voltammetric behavior of BiIII on a sodium humate modified carbon paste electrode was studied by means of cyclic voltammetry (CV) and differential pulse stripping voltammetry (DPSV). The proposed measurement involves an initial nonelectrolytic preconcentration step in which BiIII is complexed by the surface modifier in a solution of 0.05 M KNO3-0.0106 M HNO3 (pH 2.0) and a subsequent electrochemical scan step in which the preconcentrated BiIII was reduced and then oxidized promptly in supporting electrolyte of 0.5 M HNO3. The resulting DPSV anodic current was proportional to the concentration of BiIII ion over the range of 4.78 × 10-8-1.44 × 10-5 M. The detection limit was 4.78 × 10-8 M. The proposed method was used to determine bismuth in various samples. Various factors affecting the electrode behavior were also investigated at the same time.
