Passive Sampling of Ambient Nitrogen Dioxide Using Local Tubes
Nitrogen Dioxide Passive Sampler Diffusive Sampling
2013/3/11
Traditional active and automated sampling of nitrogen dioxide (NO2) monitoring techniques require expensive instrumentation which is not easily adapted for large scale monitoring by resource limited c...
Removal of Nitrogen Dioxide and Sulfur Dioxide from Air Streams by Absorption in Urea Solution
Sulfur Dioxide Removal Nitrogen Dioxide Removal Column Absorption Removal of Acid Gases Air Pollution Prevention
2013/3/12
The study focuses on the absorption rates of NO2, SO2 and a mixture of these two acid gases into urea solution in packed bed column. The absorption rate was studied as a function of absorbent temperat...
Development of a Nitrogen Dioxide Gas Sensor Based on Mid-Infrared Absorption Spectroscopy
Fiber laser Difference-frequency generation Laser spectroscopy
2009/6/9
We demonstrated a mid-IR optical NO2 monitor based on a frequency-stabilized, Yb-fiber laser pumped difference frequency generation (DFG) in a periodically poled lithium niobate (PPLN) crystal. A high...
Interaction of nitrogen dioxide with free base phthalocyanine
phthalocyanine gas sensors ab initio calculations
2011/4/27
Quantum chemical ab initio method was used to investigate interactions between NO2 and H2Pc. Four possible sites for NO2 adsorption were considered. Full geometry optimisation together with frequency ...
