説明

A variation of head-space GC was investigated to determine hydrogen sulfide in water. A stripping chamber with 10 ml of solution containing 30% H2SO4 and 20% Na2SO4 was connected to the carrier gas line between the gas flow regulator and the column of a gas chromatograph. The solution in the chamber was bubbled with the carrier gas (N2). Water samples (10100 μl) were injected through a rubber septum into the chamber with a microsyringe. Sulfide and hydrosulfide ions in the injected water were converted to free hydrogen sulfide and stripped completely with the carrier gas in several minutes. The free hydrogen sulfide was introduced into the column and detected with a flame photometric detector. This method allows the analysis of small samples of water without pretreatment and is useful for any type of water. By this method, 0.02 ppm of hydrogen sulfide in 100 μl of water can be determined.
