The disadvantages and substitution method of gas separation tube which is used in

Abstract:

article introduces the disadvantages of gas separation tube which is used in analyzing sulfide in water by color method with direct absorption in practical operation, and the advantages of KOH solution as a replacement of gas separation tube are also proposed. The feasibility of the substitution method is verified by experiment.

Key words: sulfide gas separation tube KOH solution substitution
