Summary
A new express quantitative test accurately determines hydrogen sulfide in wastewater using a colorimetric method. This reliable test offers good reproducibility for environmental monitoring.
Area of Science:
- Environmental Science
- Analytical Chemistry
Background:
- Hydrogen sulfide (H2S) is a common pollutant in wastewater.
- Accurate H2S determination is crucial for environmental protection and process control.
Purpose of the Study:
- To introduce an express quantitative test for hydrogen sulfide determination in wastewater.
- To evaluate the test's performance regarding concentration scopes and sensitivity.
- To assess the test's reproducibility.
Main Methods:
- Development of an express quantitative test.
- Application of a linear colorimetric principle.
- Testing across specified concentration ranges and sensitivities.
Main Results:
- The test is suitable for concentration scopes of 20-400 mg/l (10 mg/l sensitivity) and 10-250 mg/l (5 mg/l sensitivity).
- Excellent reproducibility was observed, with a coefficient of variation not exceeding +/- 10%.
Conclusions:
- The developed express quantitative test is a reliable method for hydrogen sulfide determination in wastewater.
- The test offers practical application in environmental analysis due to its speed and accuracy.
