Electrodeposition of PbO2 on glassy carbon electrodes: influence of ultrasound frequency

The influence of the ultrasonic frequency on the electrocrystallisation of lead dioxide on glassy carbon electrodes was studied in 1 mol dm−3 HNO3 + 0.1 mol dm−3 Pb(NO3)2 using chronoamperometry and numerical approximations of the current transients obtained. The effects of the ultrasound frequency have been compared with the effects produced by other operational variables such as electrode potential.Universidad de Alicante (project GR03-05)
