From: Degradation of progestagens by oxidation with potassium permanganate in wastewater effluents

Figure 2

Effect of temperature on the second-order decay of progestagens: a) levonorgestrel and b) its impact on measured rate constants for oxidation of progestagenic steroid hormones (SH) by permanganate. The experimental conditions were, [KMnO4]0 from 38 to 53 μM, [progestagens]0 from 2.1 to 4.1 μM in wastewater (WWTP A) at pH 8.2 and temperature ranging from 6 to 30°C. Solid lines represent the linear regression of the measured data (symbols) with their related coefficients of determination (R2) also given.
