Abstract
Recently, the exhaust gas from motorcar causes serious air pollution. Specially, nitrogen oxides not only leads to environmental problems but also causes health problems. So it is demanded to consider a countermeasure for this problem. Therefore, in order to purification the air near the road, nitrogen oxides removal system is proposed. This paper says about the prediction of absorption mechanism and its controlling rate, using a motionless gas-liquid mixer so as to make micro bubbles of sampling gas. As a result, 1) As for nitrogen dioxide absorption into water, this reaction mechanism is controlled by chemical reaction. 2) As for nitric oxide absorption into water, this reaction mechanism changes chemical reaction control region to physical desorption control region for NO ratio.
