Determination of the Henry's law constant for dimethyl sulfide in seawater

摘要

This study describes a modified method to measure the henry's law constant (Hc) of dimethyl sulfide (DMS) across air-water interface. A fixed amount of DMS was added into a 50 ml gas-tight glass syringe with are-water (seawaer or distilled water) and equilibrated twice with different volumes of air but identical volume of water. The Hc of DMS in water could be determined by measuring the concentrations of DMS in the air phases of two equilibrium by gas chromtography.
