An N ‐butylamine functionalized graphene oxide nanolayer was synthesized and characterized by ultraviolet (UV)–visible spectrometry, Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and transmission electron microscopy. Detection of iron(III) based on photoluminescence spectroscopy was investigated. The N ‐butylamine functionalized graphene oxide was shown to specifically interact with iron (III), compared with other cationic trace elements including potassium (I), sodium (I), calcium (II), chromium (III), zinc (II), cobalt (II), copper (II), magnesium (II), manganese (II), and molybdenum (VI). The quenching effect of iron (III) on the luminescence emission of N ‐butylamine functionalized graphene oxide layer was used to detect iron (III). The limit of detection (2.8 × 10 −6 M) and limit of quantitation (2.9 × 10 −5 M) were obtained under optimal conditions. Copyright © 2015 John Wiley & Sons, Ltd.
