Water contamination by micropollutants is increasing, including steroid hormones. Indiscriminate use, incorrect disposal, inefficient treatment of water and effluents, less restrictive legislation promote the effluents water, with harmful consequences for environment human health. In this work, it was evaluated use reverse osmosis in removal ethinylestradiol levonorgestrel, synthetic steroids t...

In the present work, degradation of three estrogens (17?-estradiol (E2), estrone (E1) and 17?-ethinylestradiol (EE2)) was investigated under photoactivation hydrogen peroxide persulfate. Lab-scale irradiation experiments showed that both UVA UVB radiations are able to photoactivate oxidant precursors, although is more efficient generate radicals therefore degrade targets. The efficiency precurs...
