Removal of estrogenic activity and formation of oxidation products during ozonation of 17 alpha-ethinylestradiol

This study investigated the oxidation of the oral contraceptive 17alpha-ethinylestradiol (EE2) during ozonation. First, the effect of ozone (O-3) on the estrogenic activity of aqueous solutions of EE2 was studied using a yeast estrogen screen (YES). It cou ...

Homogeneous hydrogenation of carbon dioxide and bicarbonate in aqueous solution catalyzed by water-soluble ruthenium(II) phosphine complexes

Gabor Laurenczy

The water-soluble Ru(II)-phosphine complex, [{RuCl2(mTPPMS)(2)}(2)] was found a suitable catalyst for the hydrogenation of NaHCO3 to NaHCO2 in aqueous solution under mild conditions with catalyst turnover frequencies (TOFs) in the range of 35-50 h(-1) at 5 ...

Equilibrium and kinetic aspects of soddyite dissolution and secondary phase precipitation in aqueous suspension

Janet Gordon Hering

The dissolution and transformation of soddyite ([UO2]2SiO4·2H2O) have been examined in aqueous suspension at pH 6 and 0.01 M NaNO3. Soddyite is an important component of the paragenetic sequence of secondary minerals that arises from the weathering of uran ...

Polymeric flocculant for removal of solids from aqueous suspensions or sludges containing coal

Jutta Christine Wandrey

The solids are removed from an aq. suspension contg. 4-12 g coal fines/L using a suspension of a water-sol., high-mol. wt., highly crosslinked copolymer of di-Me diallyl ammonium chloride and 0.1-3 mol.% of a crosslinked comonomer, optionally mixed with an ...

Polymeric flocculant for removal of solids from aqueous suspensions or sludges such as sewage sludge

Jutta Christine Wandrey

The solids are removed from an aq. suspension contg. 0.01-200 g solids/L using a suspension of a water-sol., high-mol. wt., highly crosslinked copolymer of di-Me diallyl ammonium chloride and 0.1-3 mol.% of a crosslinked comonomer, mixed with acryloguanami ...

Practical guidelines for the determination of oxygen transfer coefficients (KLa) with the sulfite oxidation method

Urs von Stockar

The sulfite oxidn. method was reinvestigated to establish a procedure for the measurement of O2 transfer coeff. (KLa). Co ion catalyzed oxidns., using buffered Na2SO3 solns., were conducted in an aerated, baffled tank which was fitted with a turbine impell ...
