Abstract
The concentration of an aromatic azole corrosion inhibitor in the water of an aqueous system is monitored by a fluorometric method which is based upon the measurement of the fluorescence intensity of the aromatic azole corrosion inhibitor itself, and the precise determination of concentration permits control of the dosage of such aromatic azole corrosion inhibitor.
