Abstract

This study presents two novel all-solid-state optodes, emloyed for detecting different heavy metal ions (HMIs) in waters. For this reason, PVC-based polymeric membranes, containing tetraphenylporphyrin (TPP) and Zn(II)TPP-1,3-bis(2-pyridylimino)isoindoline-Crown (ZnPC) as cation-sensitive ionophores, were embedded in nanocellulose substrate. In addition, a water-soluble porphyrin and silver nanopar-ticles (AgNPs) were doped with nanocellulose to devise an aqueous sensing suspension. The optical response of these chemical sensors displayed a successful detection of multiple HMIs.
