Development of a two-board potentiostat device for real-time detection of cadmium ion in solution
Description
Cadmium is classified as a non-essential heavy metal element as it is harmful to human health even in a trace amount. Despite the implementation of guidelines and regulations on cadmium handling, unfortunately, mortality cases among wild animals due to cadmium poisoning still occur. To effectively investigate the sources of cadmium contaminants in the environment, it is suggested to establish real-time monitoring across the area. Thus, the aim is to design and develop a potentiostat device (HMstat) with the capability to perform a square wave anodic stripping voltammetry (SWASV) method for real-time monitoring of cadmium ion detection. The design and development of the HMstat are realized by using a two-board type potentiostat which is implemented through-hole technology as an analog component and the myRIO platform as a digital component. The capability of HMstat working under constant, ramp, and SWV signals has suggested that the HMstat has a high potential to perform the SWASV method. The design files included here are: Constant_applied_potential: containing LabVIEW file of constant V_ap signal generation Ramp_applied_potential: containing LabVIEW file of ramp V_ap signal generation SWV_applied_potential: containing LabVIEW file of SWV V_ap signal generation Real-time_monitoring: containing the LabVIEW file of GUI and for signals generation and acquisition.
