Orange Peel Essential Oil as Component of a Metal Sensor for Lead (II) Ion Determination in Aqueous Solutions

Orange (Citrus sinensis) peel, a waste material was used as source of essential oil that served as component of a sensor that detects the presence of lead (II) ions in aqueous solutions. The prepared sensor was investigated in evaluating its potential as a substitute for commercially available working electrodes. The electrochemical property of the prepared sensor was evaluated using cyclic voltammetry and differential pulse anodic stripping voltammetry. Optimization of different parameters was done for possible application of the sensor as a rapid method for lead analysis of aqueous environmental samples.
