摘要

•The magnetic nanomaterial GO-Fe3O4-DTDP acts as integrate ionophore-transducer.•A covalent mode was adopted to avoid the leaching out of Fe3O4 nanoparticles.•GO-Fe3O4 hybrids improved the sensitivity of lanthanum (III) ion selective electrode.•The prepared electrode showed low detection limit and excellent Nernstian response.
