Mass transfer and reaction kinetics of NO absorption with aqueous ferrous cysteine solution in double-stirred cell
The mass transfer and reaction kinetics of the absorptio n of NO with aqueous ferrous cysteine solutions were studied in a double-stirre d cell.The result indicated that the NO absorption with Fe(Ⅱ) (CyS)_2 was a fast pseudo-first-order reaction.The second-order rate con stant was determined from experimental results and found to be 1.18×105m 3·mol-1·s-1 at pH 8.0 and 323 K.Three kinds of theoretical mode ls were used in this mass transfer with chemical reaction process, and the same expression of enhancement factors was found.A comparison was made between the ex perimental enhancement factor and the data calculated from the models.The maximu m relative deviation was less than 13%, which was reasonable in the research of gas-liquid reaction.
