Abstract : In this work the design of the synthesis of new nanomaterials adsorbent based on the coupling of magnetic nanoparticles and graphene oxide (MNPs-GO) is addressed. Both substances separately have adsorbent properties of great interest, but their use involves certain difficulties. The coupling seeks compensation for the disadvantages of both, while maintaining its excellent properties. Synthesizing the materials took place in two different routes (method 1 and method 2). In turn, both synthesized materials are functionalized with a chelating group: [1,5-bis(2-pyridyl)3-sulfophenylmethylene] thiocarbonohydrazide (PSTH). Therefore, there are two resins: 1-PSTH and 2-PSTH. The two new adsorbent nanomaterials were characterized by various analysis techniques, SEM, TEM, XPS, MS and IR. Also, the capacity of adsorption of the both resins was determined, in order to know if it is possible to apply the materials as extractants in magnetic solid phase extraction to preconcentrate analytes present at the trace level in biological and environmental samples. Keywords - Solid-phase extraction, magnetic nanoparticles, graphene oxide, chelating functional groups, TEM, XPS, IR
