And adsorption of jack bean proteins onto the amphoteric resin was studied in this paper. The amphoteric resin was in innersalt form. The results of adsorption experiments show that when the proteins are adsorpted into the amphoteric resin in the neutral phosphate buffer solution, the diffusion coefficient of protein is near twofold in 0.4 mol/L NaCl phosphate buffer solution than that in solution without salt, and the adsorption capacity of protein also rises at the same ti...

通过盐浓度对吸附的动力学和热力学影响的研究，结果表明，在中性磷酸盐缓冲液中，两性树脂吸附刀豆蛋白，有盐( 0 。4mol/L Na Cl)的比无盐的扩散系数提高将近一半，且吸附量增加，其吸附等温线的效率在最初始部分高于无 Na Cl时的；随着盐浓度( 0～ 1 mol/L Na Cl)的提高，树脂对蛋白的吸附量也变大，盐浓度提高时树脂膨胀体积的增大与蛋白吸附量的增加呈线性关系，内盐型两性树脂对大分子蛋白质的吸附作用与小分子高价离子的相似，同样是通过内盐键破裂吸附。

The specific imprinted sites could selectively rebind the template, resulting in the slower permeation of the template. And the size effect means that the smaller the size is, the faster the template transports.

特异性识别位点会选择性地识别模板分子，从而使其渗透速度减慢；尺寸效应主要体现在底物蛋白的体积越小其渗透越快。

Because of attraction between water molecule and carbonium ion, the severe contract in system volume brings about activation volume effect (the most negative A〓 observed in this work is 407cm〓mol〓), which produces subtle relationship between reaction kinetics and pressure in a certain operating region.
