摘要

The absorption of NO in aqueous solutions of KMnO4 and H2SO4 was carried out in a stirred tank reactor under atmosphere pressure. The results indicated that the absorption process was under a fast pseudo-m th reaction regime. The reaction between NO and aqueous solutions of KMnO4/H2SO4 was found to be first-order with respect both to NO and to KMnO4. The addition of H2SO4 to KMnO4 solutions increased the absorption rate of NO and increasing reaction temperature was also favorable to the absorption of NO.
