Хемосенсор для визначення Fe(III)

Abstract

У даній роботі запропоновано та синтезовано новий хемосенсор (ХС) для визначення Fe(III).

A new сhemosensor (ChS) for Fe(III) determination was proposed and synthesized. The optimal conditions of Fe(III) and ChS interaction were established. The maximum of analytical signal observed at pH 4 and (1.0-1.6)×10⁻⁴ mol/L ChS. Revealed that the introduction in the reaction medium to 20 % acetonitrile improves good spectral reproducibility and metrological characteristics. It is shown that the analytical signal Fe(III) do not affect a significant number of Cs(І), Na(І), Li(I), Mg(ІІ), Ca(ІІ), Ba(ІІ), Mn(ІІ), Ni(ІІ), Co(ІІ) and other ions. Under optimal conditions interaction built test scale and calibration graph line to 3.2 μg/ml Fe(III).
