ELETROFIAÇÃO APLICADA AO DESENVOLVIMENTO DE NANOFIBRAS ADSORVENTES VISANDO O APRIMORAMENTO DE TÉCNICAS DE (MICRO)EXTRAÇÃO EM FASE SÓLIDA

ELECTROSPINNING APPLIED TO THE DEVELOPMENT OF ADSORBENT NANOFIBERS AIMING AT IMPROVING SOLID PHASE (MICRO)EXTRACTION TECHNIQUES. The limitations and challenges associated with the complex analyte-matrixinterfering interactions make development of new sorbent materials an attractive line in several research areas, ranging from synthesis characterization to application these materials. Among different strategies for manufacturing nanomaterials, electrospinning nanofibers based on polymeric solutions incorporated into Metal-Organic Frameworks (MOFs), Molecularly Imprinted Polymers (MIPs) Nanoparticles (NPs) have represented recent years, one methods more versatile promising regard obtaining large surface area potential functionalization chemical modification. In this sense, objective contribution is highlight work aimed at electrospun applied adsorption sample preparation processes, highlighting synthetic nanofiber MOFs, MIPs NPs main perspectives applications, although little explored, solid phase extraction microextraction techniques.
