“…The fabricated sensor proved to be an excellent tool for the simultaneous detection of these contaminants, as GPL is an easily obtainable and cheap material, and the fabrication technique of the sensor is simple, and achieved in less than a minute. The product exhibited acceptable sensitivity and reproducibility and could detect the three contaminants in actual water samples [47].…”

The rapid increase in industrialization and human population is leading to critical levels of environmental pollutants, such as agrochemicals or heavy metals, which affect the preservation and integrity of ecosystems, the accessibility to drinking water sources, and the quality of the air. As such, remediation of these issues demands strategies for implementing and designing novel technologies. In that regard, nanomaterials have unique physicochemical properties that make them desirable candidates for the detection and remediation of environmental pollutants. The scope of this review is to provide an analysis of the available nanomaterials that are being used as an approach to detect and remediate hazardous residues, comprising systems such as noble metals, biosensors, cyclodextrin-based polymers, and graphene oxide nanocomposites, to name a few. Furthermore, this work discusses said nanomaterials in terms of their effectiveness, sustainability, and selectivity as a guideline for researchers wishing to indulge in this relevant study area.

This work attempts to design an elemental method for detecting heavy metals in water. The presence of heavy metals in water is a critical issue that needs a check at every level of water consumption. To facilitate the checking, a simple method needs to be identified and developed. Electrochemical sensing is essentially a surface phenomenon and requires a higher surface area for greater accuracy and reliability. We have attempted to use a readily available Cu wire for detecting Pb to 50 μM concentration with 90% reliability. It is important to note that the sensing electrode (Cu wire) utilized for this work has been employed in a facile manner that enhances the ease of use for heavy metal electrochemical sensor. Moreover, post‐usage, the replacement of sensor material for subsequent usage is easy. The low cost and simplicity of the method make it ideal for resource‐constrained environments and portability, resulting in increasing the accessibility of water quality monitoring. The study examines the reliability of a low‐cost electrode for Pb concentration detection in water samples to the concentration of 50 μM using a simple low‐cost electrochemical sensor arrangement.
