Abstract
The study of chemical interaction between biogenic silver nanoparticles and several metal (II) ions have been discussed as a practical colorimetric and plasmon resonance sensing method for the recognition of divalent Zn+2 in aqueous solutions. In this paper, the green synthesized AgNPs, using curry leave extract as a reducing agent, were characterized by a IR spectroscopy and TEM. The colour of the AgNPs colloidal solutions obtained was reddish-brown centred between 10 and 50 nm. AgNPs with spherical, triangular, and hexagonal shapes were found by TEM analyses. Despite their divergent morphologies, these AgNPs can be employed as Plasmon resonance sensors for detection of divalent Zn2+, primarily in aqueous solutions. Sensibility studies based on molar concentrations were also performed for these metal ions. These bio composites resulted to be good adsorbent materials of Zn+2 ions.
