Abstract
- Phenolic compounds such as vanillic and p‐coumaric acids are pollutants of major concern in the agro‐industrial processing, thereby their effective detection in the industrial environment is essential to reduce exposure. Herein, we present the quenching effect of these compounds on the electrochemiluminescence (ECL) of the Ru(bpy)32+/TPrA (TPrA=tri‐n‐propylamine) system at a disposable screen‐printed carbon electrode. Transient ECL profiles are obtained from multiple video frames following 1.2 V application by a smartphone‐based ECL sensor. A wide range of detection was achieved using the sensor with limit of detection of 0.26 μM and 0.68 μM for vanillic and p‐coumaric acids, respectively. The estimated quenching constants determined that the quenching efficiency of vanillic acid is at least two‐fold that of p‐coumaric acid under the current detection conditions. The present ECL quenching approach provided an effective method to detect phenolic compounds using a low‐cost, portable smartphone‐based ECL sensor.
