Abstract. Our inquiry based lab experiment involved optimizing the ideal working electrode with a novel material such as nanoparticles to detect phenol using CV (cyclic voltammetry) and DPV (differential pulse voltammetry). Students were required to learn electrochemical instrumentation and determine how to enhance the electrode response with synthesized silver nanoparticles (AgNPs) to detect phenol in water at various pH values. Our students in the undergraduate chemistry course have found the electrochemistry instrumentation with hands-on experiences rewarding to understand important environmental issues. This lab educated our students on real-world analysis/detection of common hazardous pollutants such as phenol by differential pulse voltammetry (DPV) while integrating synthesis of nanoparticles (silver nanoparticles) deposited onto a working electrode.
