Abstract:

The kinetics of ion exchange of taurine on D290 anion exchange resin was investigated. The uptake curves of taurine on D290 anion exchange resin were determined in batch stirred tanks, and the diffusion coefficient and the mass transfer coefficient were computed, and the effects of stirred velocity and experimental temperature on the rate of uptake of taurine on D290 resin were discussed. The results showed that with the experimental temperature and the stirred velocity increasing, the rate of uptake of taurine on D290 anion exchange resin increase. And with the increase of the experimental temperature, the diffusion coefficient and the mass transfer coefficient increase .With the increase of the stirred velocity, the diffusion coefficient increase and the mass transfer coefficient don’t be affected. Based on the Helfferich number of this system, the mass transfer process of taurine taken up on D290 resin is dominated by the film diffusion.
