杂多酸型药物电极对金属离子选择性规律的研究

STUDY ON REGULARITY OF PHARMACEUTICAL ION-SELECTIVE ELECTRODES BASED ON HETEROPOLYACIDS

将φ′标度推广到杂多酸型药物电极体系,通过对6种药物的杂多酸型电极对金属离子的选择性系数pK_(ij)日与干扰离子的φ′参数之间关系的研究,推导并验证了pK_(ij)值与φ′参数之间存在下面的定量关系 pK_(ij)=α+βφ′^(-1)式中,α,β是与药物种类有关的常数。

According to our studies of regularities of properties of inorganic systems. The φ′ criterion has been extended to the pharmaceutical ion-selective electrodes of hetcropolyacids. Correlation between the selective coefficients (pK_(ij)) of the pharmaceutical electrodes of heteropolyacids on metallic ions and structure parameters (φ′) of cations of metals pK_(ij)=α+βφ′^(-1) where α and β are all constants concerning kind of pharmaceuticals.
