Indirect Determination of Trace Sulfide in Water by Catalytic Kinetic Spectrophotometry;

Methods:Sulfide was indirectly determined by catalytic kinetic spectrophotometric method which was based on the inhibition effect of sulfide on the cupper catalyzed oxidation of acridine yellow by hydrogen peroxide in NH_3·H_2O-NH_4Cl buffer medium at pH 10.

A new extraction-catalytic kinetic spectrophotometric method for the indirect determination of trace sulfide was studied.

Various influence factors of mercaptan sulfur in OCT-M hydrotreated FCC naphtha are analyzed , and hydrogenation reaction temperature and H2 S content in recycle hydrogen can be considered as the key influence factors.

However, mercaptan sulfur in DCC gasoline, which has been sweetened at a low operating space velocity and concentrated by solvent extraction, cannot be detected by flame photometer detect.
