  An ion-selective electrode for measuring carbonate concentration comprising a conductive metal layer (2), a halide of said conductive metal layer (3), a carbonate ion-selective layer (4) containing ion carrier, and a buffer layer (5) containing a hydrophilic polymer binder and a buffer laminated in this order on an electrically insulating support (1), and a pair of the above electrodes. It is characterized by not having the electrolyte layer containing hydrophilic polymer binder, having the possibility of degradation of the electrolyte layer by the absorption of moisture being extremely little, and having a good stability in the course of time. In the electrode of the invention, the ion-selective layer comprised of hydrophobic organic material is directly laminated on the metal halide layer, the adhesive strength between the metal halide layer and the ion-selective layer is sufficient, the strength of the ion-selective layer is sufficiently great, and which is stable. The electrode of the invention has a sufficient buffering ability, and it requires neither operation of preliminary measurement of the pH value of aqueous liquid sample nor fixation of the pH value by adding a pH buffer to sample. Moreover, the adverse affect (measuring error) by the interfering substance such as salicylate, p-aminosalicylate or gentisate is eliminated or remarkably reduced.

  一种用于测量碳酸盐浓度的离子选择电极，包括导电金属层 (2)、所述导电金属层的卤化物 (3)、含有离子载体的碳酸盐离子选择层 (4)、依次层叠在电绝缘支架 (1) 上的含有亲水性聚合物粘合剂和缓冲剂的缓冲层 (5) 以及一对上述电极。 其特点是电解质层不含亲水性聚合物粘合剂，电解质层因吸湿而降解的可能性极小，并具有良好的长期稳定性。在本发明的电极中，由疏水性有机材料组成的离子选择层直接层压在金属卤化物层上，金属卤化物层与离子选择层之间的粘合强度足够，离子选择层的强度足够大，并且稳定。本发明的电极具有足够的缓冲能力，既不需要对水性液体样品的 pH 值进行初步测量，也不需要通过向样品中添加 pH 缓冲剂来固定 pH 值。此外，水杨酸盐、对氨基水杨酸盐或庆大霉素等干扰物质的不利影响（测量误差）也被消除或显著降低。

  An ion selective electrode (4) employing an asymmetric membrane for the potentiometric determination of ions, e.g. carbonate in biological samples is disclosed. The asymmectric membrane comprises (i) an ion selective layer (8) containing an ion selective agent and a plasticizing agent and (ii) a sample contacting hydrophilic layer (6) fused to the ion selective layer. In a preferred embodiment for determining carbonate, a cellulose triacetate (CTA) hydrophilic layer with free hydroxyl groups is fused to a cellulose triacetate ion selective layer containing trifluoroacetyl-p-butylbenzene (TFABB) as ionophore, tridodecylmethylammonium bromide (TDMAC) as ion-complexing agent, and bis(2-ethylhexyl)adipate (DOA) as plasticizer. The electrode has the advantage of being less sensitive to interferents such as salicylate, gentisate, perchlorate etc.

  本发明公开了一种采用非对称膜的离子选择电极（4），用于生物样品中离子（如碳酸盐）的电位测定。非对称膜包括：(i) 含有离子选择剂和增塑剂的离子选择层 (8)；(ii) 与离子选择层融合的样品接触亲水层 (6)。在测定碳酸盐的一个优选实施例中，具有游离羟基的三醋酸纤维素（CTA）亲水层与三醋酸纤维素离子选择层融合在一起，三醋酸纤维素离子选择层含有三氟乙酰基对丁基苯（TFABB）作为离子亲合剂，十三烷基甲基溴化铵（TDMAC）作为离子络合剂，双（2-乙基己基）己二酸酯（DOA）作为增塑剂。该电极的优点是对水杨酸盐、庆大霉素、高氯酸盐等干扰物的敏感性较低。
