10 p, 2.1 MB Use of a bioelectronic tongue for the monitoring of the photodegradation of phenolic compounds / Cetó Alsedà, Xavier (Universitat Autònoma de Barcelona. Departament de Química) ; González-Calabuig, Andreu (Universitat Autònoma de Barcelona. Departament de Química) ; Valle Zafra, Manuel del (Universitat Autònoma de Barcelona. Departament de Química)
The application of a voltammetric bioelectronic tongue for the simultaneous monitoring of catechol, m-cresol and guaiacol in wastewater is reported. Voltammetric responses obtained from an array of bulk modified (bio)sensors, containing enzymes such as tyrosinase and laccase, were combined with chemometric tools such as artificial neural networks (ANNs) for building the quantitative prediction model.

Second generation ethanol is produced from the carbohydrates released from the cell wall of bagasse and straw of sugarcane. The objective of this work is the characterization and application of a voltammetric electronic tongue using an array of glassy carbon electrodes modified with multi-walled carbon nanotubes containing metal (Paladium, Gold, Copper, Nickel and Cobalt) oxy-hydroxide nanoparticles (GCE/MWCNT/MetalsOOH) towards a simpler analysis of carbohydrates (glucose, xylose, galactose and mannose).
