Sentence examples for both the initial sulfide from inspiring English sources

In this model, both the initial sulfide composition and the fractionation during non-equilibrium oxidation are assumed to equal 0‰.

Furthermore, in the batch tests with the addition of 50 200 mg S/L sulfide at the beginning, the average SPR in the first 3 h increased with elevating initial sulfide concentration due to more polysulfide formation and reduction.

As for sulfide, while a maximal 13% of initial sulfide is lost in the system with illite, probably due to sorption, kinetic of Cr VI) reduction in the illite suspension with phenanthroline is almost identical to those in kaolinite suspension and in homogeneous system (Fig. 3 and 4b).

Also, no significant sorption of sulfide on kaolinite was observed at an initial sulfide concentration of 800 μM.

However, our activity tests were done at low initial sulfide concentrations.

(iv) Being in a reduced form, sulfide can be oxidized into either elemental sulfur or sulfate, depending on the initial ratio between sulfide and nitrite [ 85 ].
