3.1. Sonoelectroanalytical applications
The analytical application has been one of the most active fields in sonoelectrochemistry. The first work found in
literature was presented by Allen Bard in 1963 [4], however the Compton group [42-43] have reported a vast work
in several applications of sonoelectrochemistry, developing approaches to the coupling of ultrasound with
electroanalytical techniques. Metals [44] such as silver [45], nickel [46], copper [47], lead [48], inorganic ions [49]
and organic compounds, such as 5-aminosalicylic acid [50], nucleosides and nucleotides [51] have been successfully
analyzed with different sonoelectrochemical methods.
