Iron-chelating activity determination?

29 August 2023 0 6K Report

Hi everybody

I am working on iron-chelating activity using pure flavonoids (Quercetin and Rutin). I tried thiocyanate method for the determination of iron chelation but the complex formed with Fe+3 and Quercetin transform from red to green!

How can I overcome this limitation and please recommend some other colorimetric methods for determining iron-chelating activity?

Best regards
