Figure 6From: Quantifying hydrogen peroxide in iron-containing solutions using leuco crystal violetPyrite-generated H2O2 as a function of particle loadings. 1 mM EDTA was used for the 20 and 40 g/L loadings and 10 mM EDTA was used for the 80 and 160 g/L loadings. The EDTA solutions were quickly mixed with pyrite particles for about 3 s and filtered. LCV and HRP were then added to the filtrate. When catalase is added prior to LCV, H2O2 is not detected.Back to article page
