Analytical chemistry of organic sulphur

A potentiometric method for the determination of different dissolved sulphur species, including organosulphides, was proposed by Boulegue and Popoff (1979) employing titration with HgQ2 and end-point determinations with a sulphide-sensitive electrode. GLC analysis using pentafluorobenzyl 

The chemistry of organic sulphur species dissolved in oceanic waters started with the detection of sulphhydryl group containing polar compounds and hydrocarbon-like mercaptans in an anoxic fjord by Adams and Richards (1968). Dimethyl sulphide (DMS) and carbon disulphide were 

Sulphur-containing petroleum components such as benzothiophene, DBT, and naphthobenzothiophene were obtained from seawater extracts (Warner, 1975) and were related to an oil spill. The detection of diphenyl sulphone and bis-(p-chlorphenyl) sulphone in ng amounts in the Mediterranean, as well as in oxic and anoxic Baltic waters, suggests anthropogenic input (Bouchertall, 1979) — the former compound is used as wood preserving agent and ovicide.
