Figure 6From: Phenylalanine as a hydroxyl radical-specific probe in pyrite slurriesEffect of surface area on the rate of Phe degradation. Loss of 100 μM [Phe]o in 10 g/L pyrite with surface areas were 1.25 m2/g for 38 - 63 μm (size used in all other experiments) and 14 m2/g for < 38 μm particle sizes.Back to article page
