A novel method for detecting allura red based on triple-wavelength overlapping resonance Rayleigh scattering
A method is presented for the sensitive and selective determination of trace allura red (AR) with ethyl violet (EV) in drink samples, based on triple-wavelength overlapping resonance Rayleigh scattering (TWO-RRS). At pH 10.0 in a Britton-Robinson (BR) buffer medium, AR combined with EV to form an ion-association complex, which resulted in the RRS intensity getting enhanced significantly with new RRS peaks appearing at 341, 508 and 666 nm. The scattering intensities of the three peaks were proportional to the concentration of AR in the range of 0.057-5.0 mumol L-1 (0.028-2.48 mug mL-1). The detection limits for the three single peaks were 0.048 mumol L-1 (0.024 mug mL-1), 0.050 mumol L -1 (0.025 mug mL-1), and 0.057 mumol L-1 (0.028 mug mL-1), while that of the TWO-RRS method was 0.017 mumol L-1 (0.008 mug mL-1), indicating that the TWO-RRS method could detect trace AR with high sensitivity. In addition, the optimum reaction conditions and the effects of foreign substances were studied. The composition of the ion-association complex, and the reasons for the enhancement of RRS were also investigated. The proposed method was successfully applied in a real sample analysis with satisfactory results. the Partner Organisations 2014.
