Bisphenol A is not only an important chemical raw material, but also an environmental estrogen. This article examines the reactions of bisphenol A in sub-critical water. The experimental factors, such as ratio of solvent to BPA (8.0), temperature (270~330 °C), reaction time (5~60 min) and Sodium Chloride(NaOH) concentration (0~25 g·L-1) were investigated; The decomposition products were analyzed by...
Biodegradation of Reactive Red 2(RR2) by anaerobic process UASB was investigated under thermophilic condition such as 55 plusmn 1degC. The quasi-steady state of the UASB reactor was achieved after 92 running days when the conditions were as follows: hydraulic retention time (HRT) 12 h, salinity 50000 mg/L, COD 1000 mg/L, RR2 100 mg /L. The removal efficiencies of COD and RR2 were about 20% and 92%,...
We have developed a new energy/mass spectrometer for medium energy range (10-200 keV/q) ion measurements in the Earth's magnetosphere and interplanetary space. The wide field-of-view ( ~360deg fan) enables acquisition of 3-D distribution functions for all the major ions, by utilizing spacecraft spin motions. The g-factor is much larger than the previous ion mass spectrometers in the medium energy...
