Electrochemical sensor for bisphenol A based on magnetic nanoparticles decorated reduced graphene oxide

Graphene/poly(3,4-ethylenedioxythiophene)/Fe3O4 nanocomposite – An efficient oxygen reduction catalyst for the continuous electricity production from wastewater treatment microbial fuel cells

“…4i(a)) [42e44]. GO sheets exhibited a broad band at 3470 cm À1 , which is attributed to the eOH stretching vibration and the bands observed at 1728 and 1634 cm À1 correspond to the C]O and C]C stretching vibrations, respectively [45]. The characteristic bands observed at 1396 and 1096 cm À1 are ascribed to the CeO stretching vibrations of carboxyl and alkoxy groups, respectively ( Fig.…”

Nanomaterials for analysis and monitoring of emerging chemical pollutants

“…Furthermore, graphene has been hybridized or combined with other materials, such as AuNPs [84][85][86], Fe 3 O 4 NPs [87,88], tyrosinase [89,90], chitosan [91,92], ionic liquids [85,92], conducting polymer [85], MIPS [93], and mesoporous alloy [94]. Fan et al [91] used nitrogen-doped graphene sheets along with chitosan to modify a GCE for BPA detection.…”

Chemometrics-assisted cyclodextrin-enhanced excitation–emission fluorescence spectroscopy for the simultaneous green determination of bisphenol A and nonylphenol in plastics

“…These procedures employ significant amounts of organic solvents, and it should be taken into account that under relatively strong experimental conditions some plastics such as polycarbonates undergo hydrolysis yielding additional BPA amounts [19,35]. Less severe conditions have also been applied using methanol, ethanol, acetonitrile, nheptane, and a cyclohexane/2-propanol mixture [38][39][40][41][42][43][44] as extracting solvents. We adopted this latter protocol.…”
