The Ion-exchange Kinetics of SAM+/H+ System with JK110 Resin
Chen Y, Xu Z, Shen W, Lin J, Cen P
S-adenosyl-L-methionine (SAM) is an important small molecule with many medical interests. The ionexchange kinetics of SAM+/H+ system with JK110 resin has been studied in this work. The results showed that intraparticle diffusion was the rate limiting step in the ion-exchange process. A suitable model of particle diffusion has been proposed to describe the effects of pH, temperature and SAM concentration in the solution on the ion-exchange rate. By simulating experimental data with model equation, some parameters such as diffusion constant B, internal diffusion coefficient Di and activation energy Ea are obtained.
Keywords: S-adenosyl-L-methionine Separation; JK110 Resin; Exchange Velocity; Particle Diffusion Model
