Voltammetric Investigations on Ferric-Triethanolamine System for Trace Analysist

Abstract

Abstract The complexing ability of triethanolamine has been utilised to investigate Fe(III)/Fe(II) redox system at the DME. The DC polarogram of ferric iron in presence of triethanolamine displays a reversible reduction wave which has further been confirmed by cyclic-voltammetric study at a hanging mercury drop electrode. The ferric-triethanolamine complex is estimable in sub-micro levels by employing differential pulse polarography. The technique has yielded the iron contents in drinking, ground and industrial waste waters.
