Hypothesis
Can a modified mercury analyser improve the efficiency of mercury detection in samples?
Conclusion
The modified flow injection analysis system allows for rapid and efficient mercury detection with a lower sample volume requirement.
Supporting Evidence
- The modified system can analyze up to 120 samples per hour.
- The detection limit achieved was 0.2 µg/L of mercury.
- The proposed method showed satisfactory agreement with the EPA method for mercury determination.
Takeaway
This study shows a new way to test for mercury that is faster and uses less sample than older methods.
Methodology
The study involved modifying a Coleman MAS-50A Mercury Analyser to use flow injection analysis for mercury detection.
Limitations
Further studies on membrane characteristics are needed before routine use.
