<span style="font-size:14px"><span style="font-family:Arial,Helvetica,sans-serif">The application of electrochemical techniques for the determination of pharmaceutical drugs in water is reported here. The experiment is designed for use in undergraduate chemistry courses. Two most commonly used pharmaceutical drugs e.g., ibuprofen (IBP) and paracetamol (PCM) were investigated for their identification and electrochemical investigations using cyclic votlammetry (CV) and square wave (SQW) voltammetry. The major objective of this communication is to enable students to get familiar and use sophisticated electrochemical techniques. A detailed protocol for the detection of IBP and PCM is presented in this work. The developed protocol was used to study sunlight photocatalytic degradation of IBP and PCM in photocatalytic degradation experiments carried out in the presence of ZnO based photocatalyst. This easy and efficient approach can easily be included in undergraduate chemistry courses.</span></span>
