摘要：

NO is a major air pollutant from coal-fired power plants. A combined removal of SO2 and NO is a prospective process. In this paper, the absorption kinetics of NO into weakly acidic NaClO solution was studied in a stirred tank reactor. It was proven that the absorption process occurred under the fast pseudo-mth reaction regime, and the reaction was found to be first-order with respect to both NO and NaClO. When the initial pH value of NaClO solution is 5.5, it has the best performance for NO absorption. The frequency factor and the average activation energy of this reaction were 7.96x10(8)m(3)/(mol s) and 28.15kJ/mol, respectively. The absorption rate of NO increased with increasing reaction temperature.
