Abstract
Method for determining volatile thio-ether compounds in offensive odorous sediment including: pre-treating a sediment sample, extracting volatile thio-ether compounds, separating and purifying the extraction supernatant in a solid phase extraction column, eluting with ethyl acetate, and finally collecting the eluent, which is then concentrated and used for determination by gas chromatography.
