Degradation of gestodene (GES)–17α-ethinylestradiol (EE2) mixture by electrochemical oxidation

Comparing Methods of 17α-ethinylestradiol (EE2) Determination in Surface Water

We compared methods of determination of 17α-ethinyloestradiol (EE2) in surface water in Kielce, Poland. EE2 plays a role as a contraception agent and it is commonly used as an active agent in contraception pills. During studies three methods of EE2 determination were checked: TLC, HPLC, and ELISA assay. Samples of contaminated water were taken from eight points on four rivers crossing Kielce ci...

Degradation of 17- -Ethinylestradiol (EE2) using laccases isolated from the white rot fungi Lentinula edodes, Trametes versicolor, and Agaricus bisporus

Three degrading white rot fungi, Lentinula edodes (Shiitake mushroom), Trametes versicolor (Turkey Tail mushroom), and Agaricus bisporus (Portobello mushroom) were used to degrade the pharmaceutical drug 17-Ethinylestradiol (EE2). The estrogenic activity of the degradation products was examined using organic extraction assays. They were examined using LC-MS and the Portobello, Turkey Tail, and ...

Efficiency of electrochemical advanced oxidation process for degradation of antibiotic ciprofloxacin in aqueous solutions

Introduction: Since the use of antibiotics and the release of their residuals to the environment have extensively been growing, it is expected to see mutagenated and resistant bacteria, which are a serious threat to the human health and natural ecosystems. In this study, a novel electrochemical advanced oxidation process by means of the β-PbO2 was employed in order to decompose ciprofloxacin. M...

Catalytic oxidative degradation of 17α-ethinylestradiol by FeIII-TAML/H2O2: estrogenicities of the products of partial, and extensive oxidation.

The oxidative degradation of the oral contraceptive 17α-ethinylestradiol (EE(2)) in water by a new advanced catalytic oxidation process was investigated. The oxidant employed was hydrogen peroxide in aqueous solution and the catalyst was the iron tetra-amido macrocyclic ligand (Fe(III)-TAML) complex that has been designated Na[Fe(H(2)O)(B*)] (Fe(III)-B*). EE(2) (10 μM) was oxidised rapidly by t...
