Study on the Characterization of Activated Carbon and Its Effect on the Adsorption of Hg0 [PDF]
, 2011 本文探讨了苯甲酸浸渍法如何改变改性活性炭表面含氧官能团的种类与数量以及其在140℃下对烟气中Hg0的吸附作用影响。 燃煤电厂因为煤种、燃烧炉、除尘设备等不同导致Hg0的排放量不同。烟气中因Hg0的浓度低、烟道温度高增加了活性炭注入法治理Hg0污染的难度，不能使活性炭如同治理垃圾焚烧厂的汞污染排放一样可以吸附大量的汞。因此提高活性炭对烟气中Hg0的吸附能力成为解决燃煤电厂的Hg0排放污染的重要途径。 苯甲酸浸渍法制备的改性活性炭经证实有效地提高了对Hg0的饱和吸附容量。本实验安装了在N2氛围下 ...

Veterinary Dermatology, Volume 35, Issue 5, Page 479-491, October 2024.Background – Lop‐eared rabbits may be predisposed to otitis externa (OE) as a consequence of their ear conformation. Although otoscopy, otic cytological evaluation, and culture are valuable tools in dogs and cats, published data on rabbits remain lacking. Hypothesis/Objectives – This study aimed to assess the utility of otoscopy and cytological results
