Novel Eco-Friendly Synthesis of Biosilver Nanoparticles as a Colorimetric Probe for Highly Selective Detection of Fe (III) Ions in Aqueous Solution

<div>UV-Vis absorption spectra of bio-AgNP GTE without (a) and with (b) the presence of 10 <i>μ</i>M Fe (III) ions in the pH range from 2 to 11. Inset (a) picture of bio-AgNP GTE with a pH between 2 and 11. Insert (b) picture of bio-AgNP GTE with a pH range of 2 to 11 in the presence of 10 <i>μ</i>M Fe (III) ions.</div>
