A Comparative Study of Electron Beam Radiation Treatment of Quinestrol, Norethindrone and Dienestrol from Wastewater and Toxicity Test

The irradiation degradation of selected estrogens quinestrol (QS) , norethindrone (NET) and dienestrol (DS) were evaluated by electron beam . Processes using electron beam can efficiently degradate QS, NETand DS, usually at reaction dosage lower than 6KGy. Especially remarkable is the high degradation efficiency shown by oxygen saturation which is extremely favored by acidic environment. The order of the degradation rate: DS > NET> QS by different analysis methods such as HPLC. Among electron beam irradiation carried out, higher removal of 90% from solution was observed. In addition, the estrogenic activity of QS, NET and DS was carried out by rotifer test.
