摘要

The additio of scale and corrosion inhibitors to the water stream reduces corrosion and allows repeat water cycling. The minimum detection level established by this method shows that low-level quantitation of scale and corrosion inhibitors is possible, even in a high concentration of laboratory-simulated matrix. The recoveries of all of the compounds were within 15percent of the 100 ppb spike. The reproducibility of the matrix-spiked samples were all within 5percent, without internal standard correction. While there is no current EPA guideline for the amount of corrosion and scale inhibitors released into the environment, interest in the quantification of these products in released water has increased. Ion chromatography with the IonPac AS21 column afforded excellent separation, contributing to the development of a robust method for quantitation of scale and corrosion inhibitors in a high concentration anionic matrix.
