Diamond Paste Based Electrodes for the Determination of Iodide in Vitamins and Table Salt

A new class of monocrystalline diamond paste based electrodes is proposed for the determination of iodide. Natural diamond and synthetic diamonds were used for the electrodes' construction. The detection limits were very low. Bromide and chloride did not interfere in the determination of iodide...

Summary:A new class of monocrystalline diamond paste based electrodes is proposed for the determination of iodide. Natural diamond and synthetic diamonds were used for the electrodes' construction. The detection limits were very low. Bromide and chloride did not interfere in the determination of iodide. The proposed method is very reliable for the determination of iodide at very low concentration levels in vitamins and table salt (RSD<1%).
