There are strict control indexes for NOx in industries and atmosphere quality. The determination method of NOx is different from its content and its matrix. This paper introduces the source of NOx,the generating mechanism of NOx,the harm to the env ironment , the domestic and international emission standard of NOx ,pointed out count ermeasures for control of nitrogen oxide emission. The analysis and determination method of NOx were introduced, which included gas chromatography,chemiluminescence method,spectrophotometric method and Ion chromatography. In the end of this paper, brief introduction was given on the mechanism to remove NOx in the environment, such as liquid adsorption, solid adsorption, catalytic reduction method and biological methods.
