The ability of structurally different ionic liquids with cocotrimetylammonium, didecyldimethyloammonium and bis-dimethyloctylammonium cations to degrade in water and soil environments were investigated. The test in water was conducted according to OECD guidelines 301 A and 302 B. Secondary effluent from a domestic sewage treatment plant in Zabrze, Poland was used as the inoculum. The ready biodegradability...
Two degradation metabolites of benzo(a)pyrene(BaP), cis-BP4,5-dihydrodiol and cis-BP7,8-dihydrodiol, were identified using high performance liquid chromatography (HPLC) with standards. Both BaP and the two metabolites were well-known toxic compounds. The effect of a nonionic surfactant-Tween80 (TW80) on the degradation of the above three compounds by Bacillus-07, in aqueous phase, was studied. The...
Microbiological degradation of the racemic mixture, the enantiopure R- and S-fipronil was examined under both aerobic and flooded conditions in three Chinese paddy soils. The degradation kinectics and enantiomer fraction (EF) were determined by means of high-performance liquid chromatography (HPLC) with chiral Chiralcel OD-H column, while desulfinyl, sulfone and sulfide derivatives were monitored...
