Increasing of ionic strength screened the repulsive forces between protein-chitosan, protein-protein at pH 7.4. As a result, the amount of adsorbates was increased. However, higher concentration of supporting electrolyte induced the decrease in BSA adsorption for chitosan chains tended to curling to be conglobation, which resulted in fewer sites to contact with protein.

离子强度的增加，屏蔽了蛋白质与壳聚糖表面、蛋白质-蛋白质分子之间的静电斥力，使得BSA的吸附量增加；而当盐浓度大于0.1 mol/L之后，由于壳聚糖分子链的刚性变小，容易成团，与蛋白质接触面积减小，导致吸附量下降。
