Hypothesis
Can a derivatization ion chromatography method accurately determine monoethanolamine in the presence of hydrazine in steam-water circuits?
Conclusion
The developed method is sensitive and specific for determining monoethanolamine in steam generator water.
Supporting Evidence
- The limit of detection for monoethanolamine was found to be 0.1 μg/mL.
- The recovery of monoethanolamine was between 95% and 102%.
- The method was applied successfully to steam generator water samples.
Takeaway
Scientists created a new way to measure a chemical called monoethanolamine in water used in power plants, even when another chemical, hydrazine, is present.
Methodology
The method uses derivatization ion chromatography with conductometric detection to separate and measure monoethanolamine in water samples.
Limitations
The method may not be sufficient for solutions with high salt concentrations.
