Cromatografia em fase gasosa aliada a microextração em fase sólida para análise quantitativa do desempenho de hidrogenação eletrocatalítica de ciclo-hexanona através de eletrodo modificado

Abstract

The application of solid-phase microextraction (SPME) in the analysis oforganic volatile compounds is a great and growing field of research. Thecatalytic and electrocatalytic reactions studies, hydrogenation included,have also had large increase over the last decades. This work presents a method development for analyzing electrocatalytic hydrogenation products of cyclohexanone with the simple, fast and accurateSPME, coupled with standard chromatographic methods. Preliminar method optimization was made with the aid of chemometric tools.The mentioned hydrogenation was performed by coulometry, using amodified electrode coated by a poly-(N-(4-carboxy-benzyl)-pyrrole) withspread nickel metallic particles. The construction and utilization of suchelectrode were discussed. Microanalysis were also performed.
