Hypothesis
An automated system can continuously monitor inorganic and total mercury in wastewater and other waters.
Conclusion
The proposed method is suitable for continuous monitoring of mercury in water with a high sampling frequency.
Supporting Evidence
- The method allows for a sampling frequency of 20 samples per hour.
- The detection limit of the method is 0.02 µg Hg ml-1.
- Calibration curves were established for mercury concentrations up to 10 µg Hg ml-1.
Takeaway
This study shows a new way to check for mercury in water all the time, which is important for keeping our water safe.
Methodology
The method involves flow-injection analysis followed by cold-vapour atomic absorption spectrometry to measure mercury concentrations.
Limitations
Interference from other elements in water can affect the accuracy of mercury measurements.
