Abstract: | In the presence of polyethylene glycol monostearate (PEGMS), the reduction potentials for In(III) and Cd(II) become well separated in 0.1 mol dm?3 potassium chloride medium. The relationships between the currents for the ions and their concentrations are linear in the presence of PEGMS, which makes the simultaneous determination of In(III) and Cd(II) possible. |
