The experiments include deposition and stripping voltammetry of some heavy metals in aqueous solutions on Au-loop electrode at both temperatures 60 °C and room temperature. The analytical signals on heated Au-loop electrode were recorded to be much better than those obtained at room temperature and on Au-RDE at unaffected signal-to-noise-ratio. Heated Au-loop electrode replace a classic UV-Irradiation proces for Determination some heavy metals in origin river water sample. Heated Au-loop electrode work to achieve a high greatly self-cleaning effectdue to eliminate the fouling effects.
