Abstract

A two-parameter model was applied to describe the activity coefficient for a culture medium, and, compared with Henry's law for water, Henry's law fitted to experimental data, the extended UNIQUAC model, and experimental data obtained from an experimental setup system, consisting of a liquid culture media Thiobacillus (ATCC 290) with hydrogen sulfide (H2S), dimethyl sulfide (DMS), methyl mercaptan (MM), and dimethyl disulfide (DMDS), separately.
