Determination of hydrogen sulfide content in desulfurization liquid
Thread Content
Determination of the hydrogen sulfide content dissolved in the desulfurization solution, iodometric method – do the obtained results include other sulfides as well? Such as sulfur dioxide, thioethers, etc.? Won’t the result be too high like this? The determination of sulfides also uses the iodometric method, back-titration
Adding a new ammonia solution will result in the formation of zinc sulfide; the zinc sulfide precipitate is then filtered out, and iodine titration can be used to proceed.
