Absorption of NO by using aqueous KMnO4/(NH4)2CO3 solutions

The absorption process of NO into KMnO 4 /(NH 4 ) 2 CO 3 solutions was studied in a stirred tank reactor. The experimental results showed that the reaction process was a fast pseudo-m reaction. The reaction between NO and aqueous solutions of KMnO 4 /(NH 4 ) 2 CO 3 was found to be first-order with respect to NO and with respect to KMnO 4 . The frequency factor and the average activation energy of this reaction were 2.3 × 10 9 m 3 /(mol s) and 36.77 kJ/mol, respectively. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 564–568, 2013
