Treatment of Gaseous Volatile Organic Compounds in Activated Sludge System
An activated sludge aeration tank (W × L × H = 40 × 40 × 300 cm) with a set of 2 mm orifice air spargers was utilized to treat gas-borne volatile organic compounds (VOCs, toluene, p-xylene, and dichloromethane) in air streams. Effects of liquid depth, aeration intensity (G/A), overall mass transfer coefficient of oxygen in clean water (KLaO2), dimensionless Henry’s law coefficient of the tested...

متن کاملIdentification of volatile organic compounds of some Trichoderma species using static headspace gas chromatography-mass spectrometry
Fungi release wide spectrum of volatile organic compounds (VOCs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. Trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولVolatile Organic Compounds in Uremia
BACKGROUND Although "uremic fetor" has long been felt to be diagnostic of renal failure, the compounds exhaled in uremia remain largely unknown so far. The present work investigates whether breath analysis by ion mobility spectrometry can be used for the identification of volatile organic compounds retained in uremia. METHODS Breath analysis was performed in 28 adults with an eGFR ≥ 60 ml/min...
