Figure 3From: Degradation of progestagens by oxidation with potassium permanganate in wastewater effluentsSteroid hormone (SH) decay curves following oxidation with permanganate in wastewaters (WWTP A, pH 8.2 and WWTP B, pH 6.3) for progestagens. [KMnO4]0 ranged from 17 to 39 μM. Solid (WWTP A) and doted (WWTP B) lines represent the trend of the measured data (symbols).Back to article page
