Advanced Sensor for Arsenic and Fluoride Detection

Arsenic and Fluoride on the top of hazardous contaminants in water that has been exposed to root substantial effects in individuals through drinking water. It affects more than 200 million individuals spread over 50 countries and could enter the human body through the absorption of nutrient, drinking water system, inhalation, and dermic interaction. To ensure safety, it is critical not only to detect but also precisely quantify aqueous Arsenic and Fluoride. The urgent need is to develop a smart water quality testing systems that are capable of collecting real-time geolocated water quality data without the requirement for professional experience using. Synthesized nanoparticles and carbon quantum dots materials for a fluorometric detection and quick quantification of Arsenic and Fluoride in drinking water. The quantum dots mechanism has been completely defined, and the sensing mechanism has been systematically implemented. FTIR and XPS techniques are used for specific functional group determination and TEM for morphological and structural detection. Developed materials are extremely selective for Arsenic and Fluoride both, based on functional group selectivity. Synthetic Arsenic and Fluoride standards and water samples from impacted regions were used to test the sensing material’s consistency in performance. The proposed sensor detects Arsenic and Fluoride in common applications for non-expert users, especially in rural locations. The Artificial Intelligence is used for water quality monitoring.
