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 DR2000 spectrophotometer Hach Company, Loveland, CO and a laboratory method developed for field application using 3-2-pyridyl-5, 6-bis4-phenyl- sulfonic acid-1,2,4-triazine FerroZine and a portable Milton Roy Mini 20 spectrophotometer.
