Abstract

The waste water of the citrus industry is considered a high polluting agent due to its rich organic composition. On the other hand, the rapid and efficient control of these compounds in industrial processes is of high relevance for the evaluation of the reuse of biomass for more economic, strategic and environmentally friendly purposes. In this context, electrochemical sensors based on imprinted electrodes can be an alternative with reliable, fast, easy to handle and low cost responses, as they allow the development of more robust methods with high performance, portability and contaminant free surfaces. Thus, this project aims to develop electrochemical sensors based on imprinted electrodes modified with nanoporous metal materials for determination of flavonoids hesperidin, narirutine, sinensitin and naringenin. The oxidation of these analytes on the sensors of high electrical conductivity and electrocatalytic activity will provide high sensitivity and selectivity of these flavonoids in wastes of the citrus industry. In addition, it is intended to combine the portability of these sensors with the wireless communication, through the development of platforms that will allow to collect, process and send the data via wi-fi to a smartphone/laptop, aiming the application in the field and in real time, through intelligent devices, with low power consumption and robust.
