(a) Cyclic voltammetry curves recorded for base electrolyte, after addition of SPS at the concentrations 2.5, 12.5, and 50 ppm. (b) Cyclic voltammetry curves recorded for base electrolyte, after addition of MPS at the concentrations 5, 25, and 50 ppm. (c) Distribution of intensity of the fragments: SO₃⁻, CH₂SO₃⁻, CuS⁻, SO₄⁻, C₂H₃SO₃⁻, C₃H₅SO₃⁻, CuSC₃H₆SO₃⁻, Cu₂Cl₃⁻, the ratio of CH₂SO₃⁻/C₃H₅SO₃⁻, total chlorides total thiols, and the ratio of total chlorides/total thiols, along with the wire position for base electrolyte, base + 2.5 ppm SPS, base + 12.5 ppm SPS and base + 25 ppm SPS. The wire position corresponds to the applied overpotential during CV experiment. (d) Distribution of intensity of the fragments: SO₃⁻, CH₂SO₃⁻, CuS⁻, SO₄⁻, C₂H₃SO₃⁻, C₃H₅SO₃⁻, CuSC₃H₆SO₃⁻, Cu₂Cl₃⁻, the ratio of CH₂SO₃⁻/C₃H₅SO₃⁻, total chlorides total thiols and the ratio of total chlorides/total thiols along with the wire position for base electrolyte, base + 5 ppm MPS, base + 25 ppm MPS and base+ 50 ppm SPS. The wire position corresponds to the applied overpotential during CV experiment.
