Chemically treated membrane filters were evaluated to collect hydrogen sulfide and sulfur dioxide. Four chemical treatments were tested. Silver nitrate and silver nitrate-tartaric acid filters were used to collect hydrogen sulfide, and lithium hydroxide and potassium bicarbonate were used to collect sulfur dioxide. Sampling was performed using a tandem filter holder so that the test gas would pass through each filter in sequence. A pre-filter was used to remove the aerosol component. For collecting hydrogen sulfide, the silver nitrate filters had an efficiency of 84% when used with a flow rate of 1.0 liter/minute; for collecting sulfur dioxide, the lithium hydroxide filters had an efficiency of 85% at 1.0 liter/minute. It was found that the silver nitrate filters began to absorb sulfur dioxide after several days; thus, the test gas should pass through the lithium hydroxide treated filter prior to the silver nitrate treated filter.
