Selectivity Fe(III) Ion Detection8 ofUnder optimal situations, the selectivity of MSA-AuNPs toward Fe(III) ions in the Below optimal conditions, the selectivity of MSA-AuNPs toward Fe(III) ions in thepresence of satellite metal ions (Hg2+, ,Cd2+, As3+,3+ , Cu2+ , ZnPb,2+, Sn2+, Mn, Mn2+ , Co2+ ,Ba2+, , presence of satellite metal ions (Hg2+ Cd2+ , As Cu2+, Zn2+, 2+ Pb2+ , Sn2+ 2+, Co2+ Ag+, Ag+ Mo4+, ,Ni2+,4+ , Ni2+WO42-, ,Fe2+) 4and Fe2+ ) and anions NO2-, 7 2-,, and3SOCl) was studied. was Ba2+ Mo Mg2+, , Mg2+ WO 2- , anions (Cr2O72-, (Cr 3 O Cl- NO – , 42- – , and SO4 2- ) As shown in Figure 5, the color in the the colour from the MSA-AuNP recorded along with the recorded studied. As shown in Figure five, MSA-AuNP resolution and the solution absorption spectra changed spectra changed only in the presencewhich indicated a distinct coordination absorption only inside the presence in Fe(III) ions, of Fe(III) ions, which indicated a precise coordination between the MSA and the presence the presence of other metal ions, the amongst the MSA and Fe(III) ions. InFe(III) ions. Inof other metal ions, the colour from the colour of the MSA-AuNP option remained red devoid of substantial adjustments, even with MSA-AuNP remedy remained red with no considerable modifications, even with a fivefold in-a fivefold improve inside the concentration of the competing the introduction introduction of crease in the concentration in the competing metals. With metals. With all the of foreign ions, foreign on the analytical the analytical Carbendazim Autophagy signal 20 of exceed Fe(III) that for Fe(III) ions the valueions, the value ofsignal didn’t exceed did not that for 20 ofions taken in equal taken in equal concentrations (100 ng/mL). Thus, among the investigated metal ions, concentrations (100 ng/mL). Thus, among the investigated metal ions, only Fe(III) only Fe(III) brought on a rise inside the absorption ratio of A530 /A650 , which selectivity of brought on a rise within the absorption ratio of A530/A650, which confirmed the confirmed the selectivity of the proposed the proposed sensing probe.sensing probe.Figure five.

The concentration of MSA-AuNPs was five.4 ten M.As a result of the experimental operate, cross interactions with other ions inside the studied concentrations were not revealed. As for the possibility of interaction on the residues of MCA with other ions, such as aluminum, quite a few performs showed the determination of aluminum in the joint presence with copper ions [50,51]. At the very same time, in the created electrochemical systems with potentiometric detection, the same interaction of copper and aluminum ions was observed. It was shown in our method that the presence of third-party ions (copper, aluminum, Fe(II), magnesium, cobalt, and other people) didn’t interfere together with the determination of Fe(III) ions. Even so, we could.
