Abstract

In this study, Ag(I) ion-imprinted and nonimprinted (NIP) poly(hydroxyethyl methacrylate-methacryloylamidocysteine) [poly(HEMA-MAC)] polimeric film-based surface plasmon resonance (SPR) sensors were prepared for the determination of silver ions (I) (Ag(I) ions). Atomic force microscopy (AFM) and contact angle measurements were used for the characterization of Ag(I) ion-imprinted and NIP SPR sensors. Kinetic studies are the limit of detection of 0.015 nM in the Ag(I) ions concentration range ranging from 0.5 to 1000 nM. When the selectivity of Ag(I) ion-imprinted SPR sensors was compared with the competing ions as lead (II) and copper (II) ions, it was shown that Ag(I) ions were 2.74 times and 7.04 times more selective than lead (II) and copper (II) ions, respectively. The reusability and shelf life of the developed SPR sensor has shown a decrease of 12.08% compared to kinetic analyses performed after 6 months. In addition, the determination of Ag(I) ions from real water samples was made using both SPR sensor and atomic absorption spectroscopy (AAS).
