Evaluation of Colorimetric Methods for Measuring Reduced (Ferrous) Iron

Abstract

This technical note describes a comparative study of colorimetric methods for real-time measurements of ferrous iron in reservoir tailwaters. Two methods were evaluated: the 1,10 phenanthroline method for the Hach DR/2000 spectrophotometer (Hach Company, Loveland, CO) and a laboratory method developed for field application using 3-(2-pyridyl)-5, 6-bis(4-phenyl- sulfonic acid)-1,2,4-triazine (FerroZine)' and a portable Milton Roy Mini 20 spectrophotometer.
