|Abstract: ||This work has been carried out in order to determine the copper content in sugar cane spirit samples from the south of Minas Gerais, using a carbon paste electrode modified with ascorbic acid and carbon nanotubes using the square wave voltammetry technique. The following parameters were studied: Ed (deposit potencial). Td (deposit time), f (frequency), A (amplitude) and ΔEs (increment scanning). The analytical curve was built in an interval from 0.5 to 12 mg L-1 and a coefficient of linear correlation of 0.997 Three sugar cane spirit samples were analysed, which presented copper content ranging from 0.29 to 1.59 mg L-1.|
