查询词典 strength

The results show that, with the increase in ionic strength, the adsorbed amount of taurine on the resin D290, the distribution coefficient λ and the fraction of zwitterion Tau(superscript ±) all decrease, while the pH value of the solution at the equilibrium and the content of anionic taurine Tau(superscript -) increase. Moreover, it is found that, at a certain taurine concentration, the increase in ionic strength may improve the selectivity of the anion resin for taurine.

研究结果表明：(1)随着溶液离子强度的升高，阴离子树脂对牛磺酸的平衡交换吸附容量逐渐降低，牛磺酸在树脂上的分配系数λ逐渐下降；(2)随着溶液离子强度增大，达到平衡时液相的pH值升高，溶液中牛磺酸阴离子Tau含量迅速增加，而牛磺酸两性离子Tau含量迅速降低；(3)在一定的牛磺酸浓度范围内，溶液离子强度增大，有利于提高离子交换树脂对牛磺酸的选择性。
