Mechanisms of hydrogen sulfide removal with steel

In the present study, we experimentally investigated the removal of hydrogen sulfide using steel-making slag (SMS) and clarified the mechanism of hydrogen sulfide removal with the SMS. The results proved that SMS is able to remove hydrogen sulfide dissolved in water, and the maximum removal amount o

Removal of hydrogen sulfide using soil amended with

A municipal solid waste (MSW) landfill is a major source of odorous gases, such as hydrogen sulfide (H2S). To remove H2S, a novel technique was studied using ground granulated blast furnace slag (GGBS). Laboratory column tests and regeneration tests were carried out to evaluate GGBS effectiveness. Loess soil was amended with 0, 10, or 30% GGBS, compacted to a bulk density (1.54
