Abstract
Stable Cr(III) metal–organic framework (CrMOF) was prepared and characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier infrared spectroscopy (FTIR). It was found that in the presence of potassium periodate (KIO4), phenol (PN) reacted with 4-aminoantipyrine (AAP) to form red quinone imine (QI) product, and a resonance Rayleigh scattering energy transfer (RRS-ET) occurred between the acceptor QI and the donor CrMOF. With the increase of PN concentration, RRS-ET increased, and the RRS intensity at 500 nm decreased. Based on this, a new and simple RRS-ET method for the detection of PN was established, with a detection range of 0.01–0.15 mmol/L and a detection limit (DL) of 0.005 mmol/L. The new RRS-ET method was applied to the determination of PN in water. The relative standard deviation (RSD) was 0.94–7.43%, and the recovery was 97–107%.
