This paper describes recent studies in organic sonoelectrochemistry at Coventry University, including the oxidation of thiophene monoxides, degradation of dye pollutants, formation of conducting polymers and electrosynthetic modification of proteins.
This paper describes the influence of 20 kHz ultrasound upon the corrosion behaviour of zinc in NaOH electrolytes. A systematic study of the effects exerted by ultrasound on the electrochemical interface was first carried out, so as to determine the transmitted power and to characterize mass transfer at the electrode. Then attention was focused on the corrosion passivation mechanism of zinc in sonicated NaOH solutions (0.1 and 1 M). Investigations were carried out using electrochemical techniques to determine corrosion and passivation kinetics parameters. SEM analysis of the sonicated zinc surfaces provides complementary information on the oxide layer composition and structure.
Solutions of the acidic dye, Sandolan Yellow, were subjected to sonolysis, electrolysis and sonoelectrolysis. Decolourisation did not take place using ultrasound alone but was achieved using an electro-oxidation process. The rate of electro-chemical decolourisation in the absence of ultrasound was dependent on the type of electrode used, electrolyte concentration, reaction temperature and the current density. Electro-oxidation of Sandolan Yellow using platinum electrodes was enhanced using ultrasound when carried out in a semi-sealed cell, which minimised the effects of ultrasonic degassing.
