[Determination of Henry's law constants for dimethyl sulfide in seawater].
The article presents the method of determination of Henry's Law Constant(K) for dimethyl sulfide (DMS) in seawater using multiple phase equilibration/headspace gas chromatography. The method is based on the demonstration that analysis of only one phase after multiple phase equilibration give all necessary data. The values of K of DMS in seawater determined by this method was 0.089 with relative standard deviation(RSD) of 5.50% at 22 degrees C. The linear relationship between log K and w (NaCl) was log K = 0.0688.w (NaCl) - 1.3568 with correlation coefficient(r) of 0.997. The regression equation of log K against reciprocal of absolute temperature(T) was log K = -1,544.8/T + 4.2112 with r of 0.996.
