AB  - The phenolic compound trichlorophenol (TCP) is an ingredient in fungicides and 
      herbicides. This compound's high stability, bioaccumulation, toxicity, and poor 
      biodegradability result in severe environmental and biological health issues. 
      Consequently, it is crucial to have an affordable and sensitive method for 
      detecting TCP in environmental samples. In this study, alpha-phase bismuth oxide 
      microplates and polydopamine-functionalized reduced graphene oxide (alpha-Bi(2)O(3) 
      MPs/PDA-RGO) were synthesized using a simple ultrasonic method and characterized 
      with various analytical and physical characterizations. The conversion of the 
      catechol moieties present in the resulting PDA-RGO material into quinones 
      facilitates productive interactions with diverse functional groups, such as 
      hydroxyl, amine, and imine. Consequently, the compounds 2,4,6-trichlorophenol 
      (TCP) engages in electrochemical interactions with the aforementioned functional 
      groups. As a result, TCP shows more excellent selectivity on the designed 
      alpha-Bi(2)O(3) MPs/PDA-RGO/SPCE sensor. Under the optimized conditions, the sensor 
      demonstrated a lower detection limit (0.0042 muM), a limit of quantification 
      (0.0078 muM), good sensitivity (2.24 muA muM(-1) cm(2)), a wide linear range 
      (0.019-190.7 and 212.7-1649 muM), and pinpoint specificity. The efficacy of the 
      sensor is additionally validated through the accurate identification of TCP 
      residues in water, soil, and food samples.
