Nitrogen Dioxide: Nitrogen dioxide (NO2) is one of a group of highly reactive gasses known as "oxides of nitrogen," or "nitrogen oxides (NOx)." Other nitrogen oxides include nitrous acid and nitric acid. While EPA’s National Ambient Air Quality Standard covers this entire group of NOx, NO2 is the component of greatest interest and the indicator for the larger group of nitrogen oxides. NO2 forms...

Indoor air is mostly contaminated from the use of gas for heating and cooking appliances. It is well known that the oxide of nitrogen production in the combustion products is the process that not been exactly described so far on all variables which are connected with its production. The comprehensive analysis of indoor air nitrogen oxides pollution show that extent of indoor air level exposure ...

conclusions application of zinc oxide as the photocatalyst can be effective in the removal process. background one of the important achievements of the past decade was the rapid growth of industries and accordingly production of various chemical compounds. objectives this study presents a combined system of photocatalytic oxidation and absorption solution to remove nitrogen oxides from polluted...

background: nitrogen oxides occur in the atmosphere in six forms of namely: n2o , no , no2 , n2o3, n2o4 and n2o5 .among these oxides no2 is the most important air pollutant because of its relatively high toxicity and its ubiquity in ambient air. in this research griess-saltzman method was utilized for determination of nitric oxide and nitrogen dioxide in the atmosphere of different laboratories...

Nitrogen monoxide (NO) and nitrogen dioxide (NO2) are gases produced by hightemperature combustion through reactions between nitrogen and oxygen. Both nitrogen in fuel and nitrogen in the air can participate in the reactions. Formation of NO can be followed by further oxidation into NO2 in the atmosphere. NO2 is the most toxic of the nitrogen oxides (grouped generically as NOx) and it is very i...
