Iron oxide nanoparticles carried by probiotics for iron absorption: …

WebPrecise measurements of the absorbance at many wavelengths allow the identification of a substance via absorption spectroscopy, where a sample is illuminated from one side, and the intensity of the light that exits from the sample in every direction is measured. WebSolutions of iron(III) complexes are yellow or red whilst iron(II) complexes are pale green. This is because as the oxidation state of the metal increases, Δ o increases and hence the frequency of the absorption moves towards higher frequency, i.e. for iron (III) the absorption moves towards the blue end (higher energy end) of the spectrum.
