Iron (II) concentration monitoring for determining corrosion in boiler systems.

摘要

A method for determining the presence of ferrous ion in boiler waters is described. The method can be used to directly measure the rate of corrosion occurring in boiler waters, and can measure the corrosion rates in the presence of boiler water treatment chemicals. The method uses a complex formed between only ferrous ion and 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine-p,p'-disulfonic acid monohydrate reagent.
