系统地改变冲洗剂中强组分浓度、离子对试剂浓度、离子强度和pH值,实验测定了一些氨基苯磺酸类样品的保留值;通过保留值与各种参数的拟合,验证了溶质与离子对试剂具有相反电荷时应用统计热力学推导所得的保留值变化规律式的正确性。
The concentration of strong component, the concentration of ion-pair reagent, the ionic strength and the pH value were systematically changed. The retention values of some sulfanilic acid samples were determined experimentally. The retention of solute And ion-pair reagent has the opposite charge, the use of statistical thermodynamics derivation derived retention value of the correctness of the formula.
