| Application: | • Characterization of the aroma-active compounds in Xiaokeng green tea by three pretreatment methods combined with gas chromatography-olfactomet ).• Novel insights into dimethylsulfoniopropionat ).• Adsorption Mechanism and Regeneration Performance of Calcined Zeolites for Hydrogen Sulfide and Its Application.: The study explores the use of calcined zeolites for the adsorption of hydrogen sulfide, a precursor to dimethyl sulfide, and discusses the material′s regeneration performance for industrial applications (Zha et al., 2024 ). |
| General description: | Dimethyl sulfide (DMS) is a biogenic sulfur compound that is released from the ocean to the atmosphere. It forms the main component of the global sulfur cycle. The thermal decomposition behavior of dimethyl sulfide in gas phase has been investigated in a static system at 681-723K. The mechanism of its photochemical oxidation in atmosphere has been described. The rate constant of the gas phase reaction between OH radicals and DMS have been determined by relative rate methods and flash photolysis technique. The differential Raman cross section, σDMS at different excitation wavelengths has been measured. The adsorption of DMS on activated carbons (ACs) has been reported to take place by hydrogen bonding. |
