Department of Chemistry Discusses a Master’s Thesis on Developing Electrochemical Sensors for Detecting Fluoride Ion and Lead and Cadmium Ions

A master’s thesis was discussed in the Department of Chemistry at the College of Education for Pure Sciences – University of Samarra, entitled: “Development of Advanced Electrochemical Sensors for the Detection of Fluoride Ion and the Determination of Lead and Cadmium Ions Using Anodic Stripping Voltammetry,” presented by the student (Lazim Abdullah Saleh).

The aim of the thesis was to develop highly sensitive electrochemical sensing systems for detecting certain inorganic pollutants of environmental and health significance, particularly fluoride ion and heavy metal ions such as lead and cadmium in water, using advanced nanomaterials and precise electrochemical analysis techniques.

The results demonstrated the efficiency of the developed sensors in detecting the studied ions with high sensitivity and low detection limits. The linear range for the determination of lead and cadmium was between 0.5–50 µg/L, while the detection limits reached 0.09 µg/L for lead and 0.23 µg/L for cadmium, with good reproducibility. Additionally, the method was successfully applied to analyze real water samples, such as drinking water and industrial water, with satisfactory recovery values. This indicates the potential of these sensors for monitoring environmental pollutants and protecting public health.
