Determination of Sulfur Species in Oil Shale Waste Waters by Ion Chromatography

摘要

Ion chromatography was evaluated for analysis of sulfur (S) species in oil shale waste waters. Chromatographic separation of S sub 2 O sub 32- and SCN exp - , the effect of high salt concentration on the elution of SO sub 42- , and the inherent instability of S species in the samples are discussed. Several sulfur-oxide anions, including S sub 2 O sub 42- , S sub 2 O sub 52- , S sub 2 O sub 62- , and S sub 2 O sub 72- were unstable when added to solution, forming SO sub 32- , SO sub 42- . However the method proved applicable to determination of SO sub 32- , SO sub 42- , S sub 2 O sub 32- and SCN exp - in oil shale retort water and from retorted shale in both laboratory and field studies.
