Hypothesis
The study investigates the effect of photolysis on the preconcentration of copper in natural waters using an in-line digestion system.
Conclusion
The in-line digestion system significantly improves the recovery of complexed copper from natural waters.
Supporting Evidence
- Over 90% of complexed copper was recovered with the UV lamp on.
- When the UV lamp was off, recovery dropped significantly for different ligands.
- The system allows for the analysis of total copper in natural waters.
Takeaway
This study shows a new way to clean water by using light to help get rid of copper, making it easier to measure.
Methodology
The study used a flow injection system with a UV lamp and Chelex-100 ion-exchange column to analyze copper recovery.
Limitations
The detection limits of the current system are too high for comparing natural waters.
