Quantitation of the hydroxyl radical by reaction with dimethyl sulfoxide
Open accessAbstract
This investigation was conducted to validate the use of dimethyl sulfoxide (DMSO) as a quantitative molecular probe for the generation of hydroxyl radicals (HO.) in aqueous systems. Reaction of HO. with DMSO produces methane sulfinic acid as a primary product, which can be detected by a simple colorimetric assay. To evaluate this method for estimating total HO. production, we studied three model systems, including the Fenton reaction, gamma irradiation of water, and ultraviolet photolysis of hydrogen peroxide, for which the theoretical maximum yield of HO. could be calculated and compared to measured DMSO oxidation. The results confirm that 0.05 to 1 M DMSO may be used to capture nearly all of the expected HO. radicals formed. Thus, methane sulfinic acid production from DMSO holds promise as an easily measured marker for HO. formation in aqueous systems pretreated with DMSO.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
