Electrochemical Sensors Based on Schiff Base to Detect Pb(II) Ion: Recent Advancements and Future Perspectives

Schiff base has gained attention because it is highly sensitive toward metal ions. Lead, one of the heavy metals, is harmful for human health and the environment, making lead contamination a matter of concern across the globe. Hazardous effects of lead can be minimized by detecting its presence in food and water. Detection of lead ion by electrochemical sensors is gaining credence in which Schiff base is extolled as being highly selective, cost effective, and rapidly sensitive toward Pb(II). The Schiff base sensor provides a pathway to extricate the dolorous effects of lead by early detection.
