Figure 2From: Phenylalanine as a hydroxyl radical-specific probe in pyrite slurriesDegradation of various Phe concentrations in the presence of 100 g/L pyrite (Exp. A). Phe concentrations through time are fit well with exponential regressions. Controls of 307 μM Phe are also shown without pyrite in pure water and 112 μM Phe in 1000 μM H2O2; as well as with pyrite quenched with 0.1% (14.2 mM) β-ME.Back to article page
