Double Type Detection of Triiodide and Iodide Ions Using a Manganese(III) Porphyrin as Sensitive Compound
A paramagnetic A<sub>3</sub>B-type Mn(III)-porphyrin was synthesized and characterized by physical-chemical methods (UV-Vis, FT-IR, <sup>1</sup>H-NMR spectroscopy). The obtained compound was tested as a sensitive material for the spectrophotometric and potentiometric detection of iodine species. Using UV-Vis spectroscopy, the triiodide anions could be detected with high precision in the concentration interval of 1.02 × 10<sup>-5</sup> to 2.3 × 10<sup>-5</sup> M, with an LOD of 9.44 × 10<sup>-6</sup> M. The PVC-based electrode using DOP as a plasticizer showed a sensitivity toward iodide in a wide concentration range of 1.0 × 10<sup>-5</sup> to 1.0 × 10<sup>-1</sup> M, with an LOD of 8.0 × 10<sup>-6</sup> M. Both methods are simple, low-cost, and efficient for the detection of iodine species in synthetic samples and pharmaceuticals.
