Electrodeposition of PbO_2 on glassy carbon electrodes: influence of ultrasound frequency

摘要

The influence of the ultrasonic frequency on the electrocrystallisation of lead dioxide on glassy carbon electrodes was studied in 1 mol dm~(-3) HNO_3 + 0.1 mol dm~(-3) Pb(NO_3)_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.
