Application of a sorbent based on graphene oxide modified with magnetic nanoparticles for the separation of organic contaminants in wastewater.
(Sociedad Española de Química Analítica, 2024)These advantages have been further extended through the functionalization of GO with magnetic nanoparticles (MNPs), resulting in sorbents with enhanced stability and durability. Furthermore, the easy separation of GO-MNP-based ... -
Magnetic graphene molecularly imprinted polypyrrole polymer (MGO@MIPy) for electrochemical sensing of malondialdehyde in serum samples
(Elsevier, 2022-03-12)A modified screen-printed carbon electrode (SPCE) has been designed and fabricated for the determination of malondialdehyde (MDA), an important biomarker of oxidative stress. Magnetic graphene oxide (MGO) was synthesized ... -
Optimization of the mechanochemical synthesis of graphene oxide and its characterization. Application to the synthesis of magnetic graphene oxide.
(2023)Nowadays, the use of materials derived from graphene oxide (GO) is extended in the technologycal industry and research due to their excellent physico-chemical properties. This fact invites us to investigate a sustainable ... -
Semiautomatic method for the ultra-trace arsenic speciation in environmental and biological samples via magnetic solid phase extraction prior to HPLC-ICP-MS determination
(Elsevier B.V., 2021)A novel magnetic functionalized material based on graphene oxide and magnetic nanoparticles (MGO) was used to develop a magnetic solid phase extraction method (MSPE) to enrich both, inorganic and organic arsenic species ... -
Simultaneous preconcentration and determination of trace metals (V, Ni, Ti, and Ga) in environmental samples by high resolution continuum source electrothermal atomic absorption spectrometry.
(2023)In this work is presented a simple, sensitive, low-cost method for direct and simultaneous determination of V, Ti, Ni and Ga by electrothermal atomic absorption spectrometer (ETAAS) in aqueous environmental samples (tap ...
