Abstract

Rapid and simultaneous detection of Alkylresorcinols (ARs) and ferulic acid (FA) could evaluate qualities of commercial wheat products comprehensively and improving product quality. In this work, we have developed a colorimetric strategy for rapid and simultaneous detection of ARs and FA by using in-situ coupling reaction between analytes and diazotized small molecule probe in aqueous media. This strategy featured a rapid response, obvious color change, simple preprocessing, high sensitivity and selectivity. The limit of detection (LOD) can be as low as 0.244 μM and 0.5 μM for ARs and FA, respectively. The sensing mechanism was investigated by spectroscopy technique. Excellent practical application of this method was further confirmed to simultaneously monitor ARs and FA in real samples. The accuracy of the method could be reached to 95.0 % and 99.6 % for ARs and FA respectively. To our knowledge, this work firstly reported a sensor for ARs and FA simultaneous determination.
