Abstract
In order to achieve rapid detection of naphthalene content in water, the electrochemical biosensor has been developed based on microcontroller by the cyclic voltammetry (CV). The system is consisted of a three-electrode electrochemical system, converting circuit, IAP15F2K61S2 microcontroller and display unit. The voltammetric oxidation-reduction response of a bare gold electrode has been gained in a potential window from −0.3 V to +0.6V. After data acquisition and processing, according to the change of peak current of voltammograms, the naphthalene content is detected and displayed.the sensor can finish the detection of naphthalene content in 15 minutes.
