Technical Abstract: Ferrate (VI)is used as a means of breaking down and/or removing steroidal estrogens (SE) from dairy waste lagoon effluent (DWLE), to minimize the amount of SE entering groundwater/watersheds. Dairy lagoon sites were sampled for EC (estrogenic content) and assayed using High Performance Liquid Chromatography (HPLC) fractionation. Effect of Ferrate (VI) or ferric chloride treatment of DWLE on EC was analyzed by LC MS MS. Initial total concentration of extractable estrogenic compounds in DWLE was 27.70 micrograms/L. Estradiol, 19.67 micrograms/L, was the most prevalent estrogenic form and estriol, 2.10 micrograms/L the least prevalent form. When DWLE was treated with a high concentration (0.84%) of Ferrate(VI) there was a significant decrease in estradiol content (P < 0.05). Ferrate(VI) treatment of DWLE decreased the concentration of extractable estradiol logarithmically [(y = 5.75ln(x) 20.52) (R2 = 0.97)] with increasing concentration of Ferrate(VI). Ferrate(VI) treatment of DWLE may be an environmentally sound method for reduction of estrogenic compounds.
