Selective cleavage of acyclic sulphides of sulphur-rich geomacromolecules by superheated methyl iodide

, 1993
A novel selective chemical degradation method was developed to discriminate between different sulphur-bound moieties in sediments and oils. The method was tested with several geochemically relevant model compounds and with a polar and an asphaltene ...

Hydrological controls on copper, cadmium, lead and zinc concentrations in an anthropogenically polluted mangrove ecosystem, Wynnum, Brisbane, Australia

, 1997
Biogenic sulphides, particularly pyrite and hydrated iron- monosulphides, are common in sediments in mangrove ecosystems where they may provide a geochemical trap for heavy metals.

A Study of Polymer Bound Sulphur Based Antioxidants in Rubber [PDF]

A commercially available hindered phenolic antioxidant, 2,6-Ditert-butyl phenol has been converted into a mercaptan derivative, viz. 3,5-Ditert-butyl-4-hydroxy benzyl mercaptan and the latter has been successfully bound to natural rubber by a free ...

Studies of Some Sulphur Radicals by Electron Spin Resonance Spectroscopy [PDF]

The formation of organo-sulphur free radicals by the action of ultraviolet radiation on thiols and disulphides of the C1 to C4, alkanes, and certain other sulphur compounds is reported.

Distribution and partitioning of major and trace elements in pyrite-bearing sediments of a Mediterranean coastal lagoon

, 2015
The formation of iron sulphide minerals exerts significant control on the behaviour of trace elements in sediments. In this study, three short sediment cores, retrieved from the remote Antinioti lagoon (N.
