Optimization of innovative composite sensor for Pb(II) detection and capturing from water samples

In developing countries, the lack of analytical infrastructures hindering the regular quality assessments of water quality. The access to affordable, portable and easy-to-use analytical technologies for real-time and on-site water monitoring is necessary to safeguard public health and protect the environment. In this connection, ligand based composite sensor material was successfully developed for optical detection and removal of toxic lead (Pb(II)) ion from water. The fabricated sensor was exhibited the specific functionality for Pb(II) detection and removal from aqueous media in ultra-trace level. The Pb(II) ion detection limit was defined as low as 0.24 µg/L with evolving specific color formation at optimum conditions. The solution acidity was the key point for the formation of specific color after addition of Pb(II)…
