UV-Vis absorption spectra (a) of bio-AgNP GTE in the addition of 10-4 M ions (Co2+, Cu2+, Ca2+, Zn2+, Ni 2+, K +, Na +, Mn2+, NO3-, Cl-, and SO42-) and 10 μM Fe (III) ions. (b) Comparison of the absorbance rate A0/A425 of the bio-AgNP GTE with different ions. (c) A visual representation of the color change by using different ions.
