ON-LINE IRON (II) CONCENTRATION MONITORING TO CONTINUOUSLY DETERMINE CORROSION IN BOILER SYSTEMS

摘要

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