Abstract: The static state exchange and absorption properties of tartaric acid and Cl - on four types of weakly basic anion exchange resins D315,D301,D345 and 335 were investigated systematically in the present of paper.A series of dynamical exchange curves and the related equations were obtained from the experimental data,and the discussions about the relationship between the equation parameters and the resin exchange property were also included.Additionally,some influencing factors,such as temperature,the original concentration were preliminarily studied in our research too.
