Recent Advances in Microextraction Methods for Sampling and Analysis of Volatile Organic Compounds in Air: A Review
Human exposures to volatile organic compounds (VOCs) are associated with a wide range of health problems. Due to these adverse effects of VOCs on the human health, determination of trace levels of VOCs is very important for accurate assessment of indoor and outdoor exposure. Solid phase microextraction (SPME), needle trap device (NTD) and hollow fiber- liquid phase microextraction (HF-LPME) are...
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 Monitoring for Semiconductor Foundry Clean Room Air
Air samples were collected in consecutive days using Summa canisters from semiconductor foundry clean rooms and air entrances. By coupling a NuTech preconcentrator with an Agilent GC-MS, an optimized method for qualitative and quantitative analysis of VOC compounds was developed. Method detection limit (MDL), blank spike (BS) and blank spike duplicate (BSD), etc. were estimated for method valid...
متن کاملDevelopment of a Method Based on the Needle-trap Microextraction Filled with Hydroxyapatite and Polyaniline Nanocomposite for Determination of Volatile Organic Compounds in the Air
In this study, the efficiency of packed needle trap with hydroxyapatite/polyaniline (NTD-HAP/PA) nanocomposite was assessed in air sampling and analysis of a hazardous group of VOCs such as benzene, toluene, ethylbenzene and xylenes. The effects of main parameters, including desorption temperature and time, were evaluated on the performance and carryover of prepared NTDs. Moreover, the repeatab...
متن کاملPassive sampling for volatile organic compounds in indoor air-controlled laboratory comparison of four sampler types.
This article describes laboratory testing of four passive diffusive samplers for assessing indoor air concentrations of volatile organic compounds (VOCs), including SKC Ultra II, Radiello®, Waterloo Membrane Sampler (WMS) and Automated Thermal Desorption (ATD) tubes with two different sorbents (Tenax TA and Carbopack B). The testing included 10 VOCs (including chlorinated ethenes, ethanes, and ...
