Figure 2From: Adenine oxidation by pyrite-generated hydroxyl radicalsAdenine exposed to pyrite. 100 μM adenine was incubated and agitated with 10 g/L pyrite and samples were periodically withdrawn and filtered to remove the pyrite particles before wavelength scans were recorded. In separate vials, 50% EtOH (ethanol) and 64 kUnits catalase were added to pyrite/adenine suspensions.Back to article page
