Abstract

Environmental issues such as the availability of fossil fuels and environmental problems generated from its use as well as economic and geopolitical reasons put emphasis on the search for renewable energy sources and clean, these being objects of research worldwide. This search puts biofuels derived from different biomasses as sources of great potential, including ethanol. Because of this, many methods of analysis for ethanol production have been developed. Among these, the determination of total reducing sugars in various stages of the processing of sugar cane for biofuel production has great importance because it allows evaluating the quality of the raw material for the production of ethanol, as well as possible losses, so to enable production optimization aiming at a better utilization of the raw material. However, the conventional methods usually applied for such determination are not very selective and require a long analysis time and temperature control. Therefore, the objective of this project is to develop a total reducing sugars sensor, simple, fast and reliable that can be applied as an alternative to the classical methods , employing for this a glassy carbon electrode modified with graphene and copper nanoparticles using chronoamperometric methods.
