Abstract

Environmental contamination has become a major concern in many countries throughout the world. Copper, being a sort of solid waste, has the big potential to pollute the environment in a variety of ways. As a result, it is necessary to detect the presence of copper in order to take precautionary measures and prevent environmental consequences. The interdigitated electrodes (IDE) was chosen for detecting the presence of copper ions in this experiment for several reasons such as low cost, ease of manufacture, and great sensitivity. Chitosan films were used as adsorbent in order to help the IDE sensor in detecting the presence of copper in this research. Moreover, the AD5933 evaluation board and AD5933 Eval Software were used in this work measurement to detect the presence of copper ion in the copper solution by measuring the value of parameters to allow for portability of the measurement. The best parameter to be used in this method has been determined which is imaginary part of impedance, as it has the value the highest sensitivity of measurement with the value of gradient equal to 84.966, and also has high value of regression or R2 that is 0.713 which indicates a high exactness in measurement as the value is close to 1.
