15 صفحه اولEnhanced removal of ethylbenzene from gas streams in biotrickling filters by Tween-20 and Zn(II).
The effects of Tween-20 and Zn(II) on ethylbenzene removal were evaluated using two biotrickling filters (BTFs), BTF1 and BTF2. Only BTF1 was fed with Tween-20 and Zn(II). Results show that ethylbenzene removal decreased from 94% to 69% for BTF1 and from 74% to 54% for BTF2 with increased organic loading from 64.8 to 189.0 g ethylbenzene/(m³·hr) at EBRT of 40 sec. The effect of EBRT (60-15 sec)...
متن کاملRemoval of Cr(VI) Species from Aqueous Solution by Different Nanoporous Materials
Background: The removal of toxic metals from sewage and wastewaters is one of the most important concerns in the twenty first century. The removal of poisonous Cr(VI) from aqueous solution by different low-cost available nanoporous adsorbents was investigated in the present study. Methods: Fumed silica, bentonite (BN), hydrotalcite (HT), MCM-41, Na-Y, mordenite (MOR) and SAPO-34 were ...
متن کاملAdriamycin: protection from cell death by removal of extracellular drug.
Adriamycin is a cytotoxic drug which has enjoyed considerable success in the treatment of cancer. This agent has a bewildering variety of biological effects both within and on the surface of cells exposed to drug, and it has proved difficult to unambiguously assign a single mechanism of action. In this report we are able to separate intracellular and extracellular actions by taking advantage of...
