A. Paytan thesis University of California San Diego (1995).
Barite was separated from sediments by sequential leaching. The marine sediments were first leached with 6 N HCl in a glove bag under a N 2 atmosphere to remove the carbonate and sulfides. After ∼12 hours the acid was washed by centrifugation and the samples were treated as described (16 17).
Barite was reacted with a reducing solution (HCl-HI-H 3 PO 2 ) that converts barite sulfur to H 2 S at 100% efficiency. The evolved H 2 S was continually swept with a high-purity nitrogen carrier gas through a 0.2 M cadmium acetate trap. Hydrogen sulfide reacts with cadmium acetate to form CdS; its S was subsequently converted to Ag 2 S by overnight reaction with 0.1 M AgNO 3 . After yield determination Ag 2 S sulfur was converted to SF 6 by reaction with BrF 5 in a nickel reaction manifold. The reaction was carried out at 800°C for 12 hours with a 150-fold excess of BrF 5 . After this reaction the SF 6 was cryogenically purified by passage through a series of three traps at –118°C. A final purification was accomplished by means of a HP 5890A gas chromatograph (12 foot Porpak Q column). This final purification ensured the highest SF 6 purity. Three sulfur isotope ratios were measured ( 36 S/ 34 S 34 S/ 32 S 33 S/ 32 S) using a Finnigan MAT 252 triple-collector isotope ratio mass spectrometer. On the basis of >1000 sample and standard analyses the precision and accuracy for δ 34 S is 0.20 per mil. This includes the entire chemical extraction procedure conversion to silver sulfide purification and mass spectrometry.
