摘要：

The iron(II) bis(2,3-dimercapto-1-propanesulfonate) (Fe2+(DMPS)(2)) complex is a newly developed metal thiochelate for the removal of NOx from flue gas. The mass transfer and kinetics of the absorption of NO in aqueous Fe2+(DMPS)(2) solutions have been studied in a stirred reactor. Factors influencing the NO absorption rate, such as pH, Fe2+(DMPS)(2) concentration, and the ratio of Fe2+ to DMPS have been investigated. The forward rate constant of the Fe2+(DMPS)(2)NO complexation reaction has been determined to be 1.1 x 10(8) L/mols at pH 7.2 and 50 degrees C.
