Hypothesis
The study aims to develop a continuous-flow method for the determination of nitrate and phosphate in water.
Conclusion
The proposed methods allow for the automated monitoring of phosphate and nitrate in sea-water samples, facilitating routine daily determinations in fish farms.
Supporting Evidence
- The method allows for the determination of phosphate in the range of 1-20 µg/ml and nitrate between 5 and 100 µg/ml.
- The analytes can be determined at a rate of 45 samples per hour.
- The results from the proposed methods were consistent with those from batch methods.
- The method provides a high degree of automation for monitoring nutrients in aquaculture.
Takeaway
This study created a way to quickly check the nutrients in water for fish farms, helping to keep the fish healthy.
Methodology
A continuous-flow method using a programmable switching valve to insert reagents and sample solutions for the determination of nitrate and phosphate.
