Sulfate Reduction

Field:

Sediment subcores are sampled in 26 mm ID acrylic tubes with injection ports filled with silicone rubber.

Laboratory:

The weight of each vial + sediment + ZnAc is determined and the average weight of the empty vial subtracted.

The samples are centrifuged (4500 rpm, 5 min; sandy sediments 6000 rpm) and the supernatant carefully removed and kept for further analysis.

35SO42- radioactivity of the supernatant is determined on a 0.1 ml sample in 1 ml H2O and 7 ml Lumasafe plus (Lumac BV.) in the scintillation counter.
