Issues related to the detection of sulfides in wastewater
Thread Content
What is the adjudicative method in the testing methods for sulfides in wastewater? Additionally, we tested the wastewater reused in oil fields using both a water quality analyzer and a sulfur detection tube, and the data obtained from testing the same wastewater varied significantly; we’re not sure why I hope experts can give some advice. Thank you all!
The common methods for detecting sulfides include the methylene blue colorimetric method, the iodometric titration method, and the electrode potential method. Different instruments have different sources of interference; moreover, it is best to conduct the test several times to determine whether the issue is caused by human factors or by the instrument itself.
