H2S pollution: a gulf war problem. prediction of Henry's constant for H2S under simple experimental conditions

One of the major concerns after the Iraqi invasion was the possibility of air pollution due to the presence of many volatile contaminants emitted from sewage tanks and pipeline. Hydrogen sulfide (H₂S) was one of the major contaminants and was a common cause of complaint from the residents in the Ardiya district in Kuwait.

In this study an effort was made to develop an apparatus for the estimation of Henry's constant (H) for H₂S. The accuracy of this instrument was counter checked with respect to published data. The experiments could be reproduced with a maximum error of 10%. The experiments were performed between 20–40°C. Henry's constants for the sewage water were found to be 600, 720 and 905 atm/mole at 20, 30 and 40°C. The values were compared to the literature values and were found to be on the higher side, indicating a need for remedial measures.
